37 * devices may have more than one channel e.g. "foo_tx"

39 * channel (for platforms supporting muxed signals). If you have
40 * static assignments, make sure this is set to the assigned signal
41 * number, PL08x have 16 possible signals in number 0 thru 15 so
42 * when these are not enough they often get muxed (in hardware)
43 * disabling simultaneous use of the same channel for two devices.
44 * @max_signal: the maximum DMA signal number to be muxed in for
45 * the channel. Set to the same as min_signal for
46 * devices with static assignments
47 * @muxval: a number usually used to poke into some mux regiser to
48 * mux in the signal to this channel
49 * @cctl_opt: default options for the channel control register
50 * @addr: source/target address in physical memory for this DMA channel,
51 * can be the address of a FIFO register for burst requests for example.
52 * This can be left undefined if the PrimeCell API is used for configuring
53 * this.
54 * @circular_buffer: whether the buffer passed in is circular and
55 * shall simply be looped round round (like a record baby round
56 * round round round)
57 * @single: the device connected to this channel will request single DMA
58 * transfers, not bursts. (Bursts are default.)
59 * @periph_buses: the device connected to this channel is accessible via
60 * these buses (use PL08X_AHB1 | PL08X_AHB2).

493/**
494 * struct device - The basic device structure
495 * @parent: The device's "parent" device, the device to which it is attached.
496 * In most cases, a parent device is some sort of bus or host
497 * controller. If parent is NULL, the device, is a top-level device,
498 * which is not usually what you want.
499 * @p: Holds the private data of the driver core portions of the device.
500 * See the comment of the struct device_private for detail.
501 * @kobj: A top-level, abstract class from which other classes are derived.
502 * @init_name: Initial name of the device.
503 * @type: The type of device.
504 * This identifies the device type and carries type-specific
505 * information.
506 * @mutex: Mutex to synchronize calls to its driver.
507 * @bus: Type of bus device is on.
508 * @driver: Which driver has allocated this
509 * @platform_data: Platform data specific to the device.
510 * Example: For devices on custom boards, as typical of embedded
511 * and SOC based hardware, Linux often uses platform_data to point
512 * to board-specific structures describing devices and how they
513 * are wired. That can include what ports are available, chip
514 * variants, which GPIO pins act in what additional roles, and so
515 * on. This shrinks the "Board Support Packages" (BSPs) and
516 * minimizes board-specific #ifdefs in drivers.
517 * @power: For device power management.
518 * See Documentation/power/devices.txt for details.
519 * @pwr_domain: Provide callbacks that are executed during system suspend,
520 * hibernation, system resume and during runtime PM transitions
521 * along with subsystem-level and driver-level callbacks.
522 * @numa_node: NUMA node this device is close to.
523 * @dma_mask: Dma mask (if dma'ble device).
524 * @coherent_dma_mask: Like dma_mask, but for alloc_coherent mapping as not all
525 * hardware supports 64-bit addresses for consistent allocations
526 * such descriptors.
527 * @dma_parms: A low level driver may set these to teach IOMMU code about
528 * segment limitations.
529 * @dma_pools: Dma pools (if dma'ble device).
530 * @dma_mem: Internal for coherent mem override.
531 * @archdata: For arch-specific additions.
532 * @of_node: Associated device tree node.
533 * @devt: For creating the sysfs "dev".
534 * @devres_lock: Spinlock to protect the resource of the device.
535 * @devres_head: The resources list of the device.
536 * @knode_class: The node used to add the device to the class list.
537 * @class: The class of the device.
538 * @groups: Optional attribute groups.
539 * @release: Callback to free the device after all references have
540 * gone away. This should be set by the allocator of the
541 * device (i.e. the bus driver that discovered the device).
542 *
543 * At the lowest level, every device in a Linux system is represented by an
544 * instance of struct device. The device structure contains the information
545 * that the device model core needs to model the system. Most subsystems,
546 * however, track additional information about the devices they host. As a
547 * result, it is rare for devices to be represented by bare device structures;
548 * instead, that structure, like kobject structures, is usually embedded within
549 * a higher-level representation of the device.

36 * Platform data is used to setup the sensor chip. Meaning of the different
37 * chip features can be found from the data sheet. It is publicly available
38 * at www.st.com web pages. Currently the platform data is used
39 * only for the 8 bit device. The 8 bit device has two wake up / free fall
40 * detection units and click detection unit. There are plenty of ways to
41 * configure the chip which makes is quite hard to explain deeper meaning of
42 * the fields here. Behaviour of the detection blocks varies heavily depending
43 * on the configuration. For example, interrupt detection block can use high
44 * pass filtered data which makes it react to the changes in the acceleration.
45 * Irq_flags can be used to enable interrupt detection on the both edges.
46 * With proper chip configuration this produces interrupt when some trigger
47 * starts and when it goes away.

21 * This driver is based on max8998.h
22 *
23 * MAX8997 has PMIC, MUIC, HAPTIC, RTC, FLASH, and Fuel Gauge devices.
24 * Except Fuel Gauge, every device shares the same I2C bus and included in
25 * this mfd driver. Although the fuel gauge is included in the chip, it is
26 * excluded from the driver because a) it has a different I2C bus from
27 * others and b) it can be enabled simply by using MAX17042 driver.

39 * struct dw_mci - MMC controller state shared between all slots
40 * @lock: Spinlock protecting the queue and associated data.

43 * @pio_offset: Offset into the current scatterlist entry.
44 * @cur_slot: The slot which is currently using the controller.
45 * @mrq: The request currently being processed on @cur_slot,
46 * or NULL if the controller is idle.
47 * @cmd: The command currently being sent to the card, or NULL.
48 * @data: The data currently being transferred, or NULL if no data
49 * transfer is in progress.
50 * @use_dma: Whether DMA channel is initialized or not.
51 * @sg_dma: Bus address of DMA buffer.
52 * @sg_cpu: Virtual address of DMA buffer.
53 * @dma_ops: Pointer to platform-specific DMA callbacks.
54 * @cmd_status: Snapshot of SR taken upon completion of the current
55 * command. Only valid when EVENT_CMD_COMPLETE is pending.
56 * @data_status: Snapshot of SR taken upon completion of the current
57 * data transfer. Only valid when EVENT_DATA_COMPLETE or
58 * EVENT_DATA_ERROR is pending.
59 * @stop_cmdr: Value to be loaded into CMDR when the stop command is

61 * @dir_status: Direction of current transfer.
62 * @tasklet: Tasklet running the request state machine.
63 * @card_tasklet: Tasklet handling card detect.
64 * @pending_events: Bitmask of events flagged by the interrupt handler
65 * to be processed by the tasklet.
66 * @completed_events: Bitmask of events which the state machine has
67 * processed.
68 * @state: Tasklet state.
69 * @queue: List of slots waiting for access to the controller.
70 * @bus_hz: The rate of @mck in Hz. This forms the basis for MMC bus
71 * rate and timeout calculations.
72 * @current_speed: Configured rate of the controller.
73 * @num_slots: Number of slots available.
74 * @pdev: Platform device associated with the MMC controller.
75 * @pdata: Platform data associated with the MMC controller.
76 * @slot: Slots sharing this MMC controller.
77 * @data_shift: log2 of FIFO item size.
78 * @push_data: Pointer to FIFO push function.
79 * @pull_data: Pointer to FIFO pull function.
80 * @quirks: Set of quirks that apply to specific versions of the IP.
81 *
82 * Locking
83 * =======
84 *
85 * @lock is a softirq-safe spinlock protecting @queue as well as
86 * @cur_slot, @mrq and @state. These must always be updated
87 * at the same time while holding @lock.
88 *
89 * The @mrq field of struct dw_mci_slot is also protected by @lock,
90 * and must always be written at the same time as the slot is added to
91 * @queue.
92 *
93 * @pending_events and @completed_events are accessed using atomic bit
94 * operations, so they don't need any locking.
95 *
96 * None of the fields touched by the interrupt handler need any
97 * locking. However, ordering is important: Before EVENT_DATA_ERROR or
98 * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
99 * interrupts must be disabled and @data_status updated with a
100 * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
101 * CMDRDY interrupt must be disabled and @cmd_status updated with a
102 * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
103 * bytes_xfered field of @data must be written. This is ensured by
104 * using barriers.

43 * DOC: Frame transmission/registration support
44 *
45 * Frame transmission and registration support exists to allow userspace
46 * management entities such as wpa_supplicant react to management frames
47 * that are not being handled by the kernel. This includes, for example,
48 * certain classes of action frames that cannot be handled in the kernel
49 * for various reasons.
50 *
51 * Frame registration is done on a per-interface basis and registrations
52 * cannot be removed other than by closing the socket. It is possible to
53 * specify a registration filter to register, for example, only for a
54 * certain type of action frame. In particular with action frames, those
55 * that userspace registers for will not be returned as unhandled by the
56 * driver, so that the registered application has to take responsibility
57 * for doing that.
58 *
59 * The type of frame that can be registered for is also dependent on the
60 * driver and interface type. The frame types are advertised in wiphy
61 * attributes so applications know what to expect.
62 *
63 * NOTE: When an interface changes type while registrations are active,
64 * these registrations are ignored until the interface type is
65 * changed again. This means that changing the interface type can
66 * lead to a situation that couldn't otherwise be produced, but
67 * any such registrations will be dormant in the sense that they
68 * will not be serviced, i.e. they will not receive any frames.
69 *
70 * Frame transmission allows userspace to send for example the required
71 * responses to action frames. It is subject to some sanity checking,
72 * but many frames can be transmitted. When a frame was transmitted, its
73 * status is indicated to the sending socket.
74 *
75 * For more technical details, see the corresponding command descriptions
76 * below.

79/**
80 * DOC: Virtual interface / concurrency capabilities
81 *
82 * Some devices are able to operate with virtual MACs, they can have
83 * more than one virtual interface. The capability handling for this
84 * is a bit complex though, as there may be a number of restrictions
85 * on the types of concurrency that are supported.
86 *
87 * To start with, each device supports the interface types listed in
88 * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
89 * types there no concurrency is implied.
90 *
91 * Once concurrency is desired, more attributes must be observed:
92 * To start with, since some interface types are purely managed in
93 * software, like the AP-VLAN type in mac80211 for example, there's
94 * an additional list of these, they can be added at any time and
95 * are only restricted by some semantic restrictions (e.g. AP-VLAN
96 * cannot be added without a corresponding AP interface). This list
97 * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
98 *
99 * Further, the list of supported combinations is exported. This is
100 * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
101 * it exports a list of "groups", and at any point in time the
102 * interfaces that are currently active must fall into any one of
103 * the advertised groups. Within each group, there are restrictions
104 * on the number of interfaces of different types that are supported
105 * and also the number of different channels, along with potentially
106 * some other restrictions. See &enum nl80211_if_combination_attrs.
107 *
108 * All together, these attributes define the concurrency of virtual
109 * interfaces that a given device supports.

2283 * @NL80211_IFACE_COMB_MAXNUM: u32 attribute giving the total number of
2284 * interfaces that can be created in this group. This number doesn't
2285 * apply to interfaces purely managed in software, which are listed
2286 * in a separate attribute %NL80211_ATTR_INTERFACES_SOFTWARE.
2287 * @NL80211_IFACE_COMB_STA_AP_BI_MATCH: flag attribute specifying that
2288 * beacon intervals within this group must be all the same even for
2289 * infrastructure and AP/GO combinations, i.e. the GO(s) must adopt
2290 * the infrastructure network's beacon interval.

2296 * Examples:
2297 * limits = [ #{STA} <= 1, #{AP} <= 1 ], matching BI, channels = 1, max = 2
2298 * => allows an AP and a STA that must match BIs
2299 *
2300 * numbers = [ #{AP, P2P-GO} <= 8 ], channels = 1, max = 8
2301 * => allows 8 of AP/GO
2302 *
2303 * numbers = [ #{STA} <= 2 ], channels = 2, max = 2
2304 * => allows two STAs on different channels
2305 *
2306 * numbers = [ #{STA} <= 1, #{P2P-client,P2P-GO} <= 3 ], max = 4
2307 * => allows a STA plus three P2P interfaces
2308 *
2309 * The list of these four possiblities could completely be contained
2310 * within the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute to indicate
2311 * that any of these groups must match.
2312 *
2313 * "Combinations" of just a single interface will not be listed here,
2314 * a single interface of any valid interface type is assumed to always
2315 * be possible by itself. This means that implicitly, for each valid
2316 * interface type, the following group always exists:
2317 * numbers = [ #{<type>} <= 1 ], channels = 1, max = 1

22 * in two 8-bit samples, "BE" or "LE" specify in which order those samples are
23 * transferred over the bus: "LE" means that the least significant bits are
24 * transferred first, "BE" means that the most significant bits are transferred
25 * first, and "PADHI" and "PADLO" define which bits - low or high, in the

27 *
28 * The pixel codes are grouped by type, bus_width, bits per component, samples
29 * per pixel and order of subsamples. Numerical values are sorted using generic
30 * numerical sort order (8 thus comes before 10).
31 *

63 * (XZ_PREALLOC or XZ_DYNALLOC).
64 * @XZ_STREAM_END: Operation finished successfully.
65 * @XZ_UNSUPPORTED_CHECK: Integrity check type is not supported. Decoding
66 * is still possible in multi-call mode by simply
67 * calling xz_dec_run() again.
68 * Note that this return value is used only if
69 * XZ_DEC_ANY_CHECK was defined at build time,
70 * which is not used in the kernel. Unsupported
71 * check types return XZ_OPTIONS_ERROR if
72 * XZ_DEC_ANY_CHECK was not defined at build time.
73 * @XZ_MEM_ERROR: Allocating memory failed. This return code is
74 * possible only if the decoder was initialized
75 * with XZ_DYNALLOC. The amount of memory that was
76 * tried to be allocated was no more than the
77 * dict_max argument given to xz_dec_init().
78 * @XZ_MEMLIMIT_ERROR: A bigger LZMA2 dictionary would be needed than
79 * allowed by the dict_max argument given to
80 * xz_dec_init(). This return value is possible
81 * only in multi-call mode (XZ_PREALLOC or
82 * XZ_DYNALLOC); the single-call mode (XZ_SINGLE)
83 * ignores the dict_max argument.
84 * @XZ_FORMAT_ERROR: File format was not recognized (wrong magic
85 * bytes).
86 * @XZ_OPTIONS_ERROR: This implementation doesn't support the requested
87 * compression options. In the decoder this means
88 * that the header CRC32 matches, but the header
89 * itself specifies something that we don't support.
90 * @XZ_DATA_ERROR: Compressed data is corrupt.
91 * @XZ_BUF_ERROR: Cannot make any progress. Details are slightly
92 * different between multi-call and single-call
93 * mode; more information below.
94 *
95 * In multi-call mode, XZ_BUF_ERROR is returned when two consecutive calls
96 * to XZ code cannot consume any input and cannot produce any new output.
97 * This happens when there is no new input available, or the output buffer
98 * is full while at least one output byte is still pending. Assuming your
99 * code is not buggy, you can get this error only when decoding a compressed
100 * stream that is truncated or otherwise corrupt.
101 *
102 * In single-call mode, XZ_BUF_ERROR is returned only when the output buffer
103 * is too small or the compressed input is corrupt in a way that makes the
104 * decoder produce more output than the caller expected. When it is
105 * (relatively) clear that the compressed input is truncated, XZ_DATA_ERROR
106 * is used instead of XZ_BUF_ERROR.

157 * or 2^n + 2^(n-1) bytes (the latter sizes are less common
158 * in practice), so other values for dict_max don't make sense.
159 * In the kernel, dictionary sizes of 64 KiB, 128 KiB, 256 KiB,
160 * 512 KiB, and 1 MiB are probably the only reasonable values,

163 *
164 * Single-call mode (XZ_SINGLE): xz_dec_run() decodes the whole stream at
165 * once. The caller must provide enough output space or the decoding will
166 * fail. The output space is used as the dictionary buffer, which is why
167 * there is no need to allocate the dictionary as part of the decoder's
168 * internal state.
169 *
170 * Because the output buffer is used as the workspace, streams encoded using
171 * a big dictionary are not a problem in single-call mode. It is enough that
172 * the output buffer is big enough to hold the actual uncompressed data; it
173 * can be smaller than the dictionary size stored in the stream headers.

175 * Multi-call mode with preallocated dictionary (XZ_PREALLOC): dict_max bytes
176 * of memory is preallocated for the LZMA2 dictionary. This way there is no
177 * risk that xz_dec_run() could run out of memory, since xz_dec_run() will
178 * never allocate any memory. Instead, if the preallocated dictionary is too
179 * small for decoding the given input stream, xz_dec_run() will return
180 * XZ_MEMLIMIT_ERROR. Thus, it is important to know what kind of data will be
181 * decoded to avoid allocating excessive amount of memory for the dictionary.
182 *
183 * Multi-call mode with dynamically allocated dictionary (XZ_DYNALLOC):
184 * dict_max specifies the maximum allowed dictionary size that xz_dec_run()
185 * may allocate once it has parsed the dictionary size from the stream
186 * headers. This way excessive allocations can be avoided while still
187 * limiting the maximum memory usage to a sane value to prevent running the
188 * system out of memory when decompressing streams from untrusted sources.
189 *
190 * On success, xz_dec_init() returns a pointer to struct xz_dec, which is
191 * ready to be used with xz_dec_run(). If memory allocation fails,
