* [ARM] 4489/1: pxa: split pxa_cpu_suspend to processor specific onesEric Miao2007-07-20
| | | | | | | | | | | | | | | | 1. split pxa_cpu_suspend to pxa25x_cpu_suspend and pxa27x_cpu_suspend and make pxa25x_cpu_pm_enter() and pxa27x_cpu_pm_enter() to invoke the corresponding _suspend functions, thus remove all those ugly #ifdef .. #endif out of sleep.S 2. move the declarations of those suspend functions to pm.h note: this is not a clean enough solution until all the pxa25x and pxa27x specific part is further removed out of sleep.S, sleep.S is supposed to contain generic code only Signed-off-by: eric miao <eric.y.miao@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4488/1: pxa: move pxa25x/pxa27x specific code out of pm.cEric Miao2007-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. introduce a structure pxa_cpu_pm_fns for pxa25x/pxa27x specific operations as follows: struct pxa_cpu_pm_fns { int save_size; void (*save)(unsigned long *); void (*restore)(unsigned long *); int (*valid)(suspend_state_t state); void (*enter)(suspend_state_t state); } 2. processor specific registers saving and restoring are performed by calling the corresponding (*save) and (*restore) 3. pxa_cpu_pm_fns->save_size should be initialized to the required size for processor specific registers saving, the allocated memory address will be passed to (*save) and (*restore) memory allocation happens early in pxa_pm_init(), and save_size should be assigned prior to this (which is usually true, since pxa_pm_init() happens in device_initcall() 4. there're some redundancies for those SLEEP_SAVE_XXX and related macros, will be fixed later, one way possible is for the system devices to handle the specific registers saving and restoring Signed-off-by: eric miao <eric.y.miao@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 4451/1: pxa: make dma.c generic and remove cpu specific dma codeEric Miao2007-07-12
| | | | | | | | | | | | | | | | | | | | | | Since the number of dma channels varies between pxa25x and pxa27x, it introduces some specific code in dma.c. This patch moves the specific code to pxa25x.c and pxa27x.c and makes dma.c more generic. 1. add pxa_init_dma() for dma initialization, the number of channels are passed in by the argument 2. add a "prio" field to the "struct pxa_dma_channel" for the channel priority, and is initialized in pxa_init_dma() 3. use a general priority comparison with the channels "prio" field so to remove the processor specific pxa_for_each_dma_prio macro, this is not lightning fast as the original one, but it is acceptable as it happens when requesting dma, which is usually not so performance critical Signed-off-by: eric miao <eric.miao@marvell.com> Acked-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 4434/1: PXA: remove PXA_IRQ_SKIPEric Miao2007-07-12
| | | | | | | | | | | | | 1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ starts from zero. This makes IRQ numbering inconsistent between PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX definition has the same value on both PXA25x and PXA27x. 2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this avoids unintentional use of these macros on PXA25x Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * [ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXXEric Miao2007-04-21

CKEN24_CAMERA --> CKEN_CAMERA The reasons for the change of these defitions are: 1. they do not scale - they are currently valid for pxa2xx, but definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera instead of bit 24 2. they are unnecessary - the peripheral name within the definition has already announced its usage, we don't need those bit numbers to know which peripheral we are going to enable/disable clock for 3. they are inconvenient - think about this: a driver programmer for pxa has to remember which bit in the CKEN register to turn on/off Another change in the patch is to make the definitions equal to its clock bit index, so that #define CKEN_CAMERA (24) instead of #define CKEN_CAMERA (1 << 24) this change, however, will add a run-time bit shift operation in pxa_set_cken(), but the benefit of this change is that it scales when bit index exceeds 32, e.g., pxa3xx has two registers CKENA and CKENB, totally 64 bit for this, suppose CAMERA clock enabling bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10) and so that pxa_set_cken() need minimum change to adapt to that.

| * [ARM] 4246/1: i2c-pxa: add adapter class to platform specific dataMatej Kenda2007-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reposted patch for kernel 2.6.21-rc2. The driver i2c-pxa doesn't set the class member in i2c_adapter, which is used to register the I2C adapter. The hwmon (sensors) drivers (e.g. adm1021) that are connected to a i2c-pxa adapter don't attach because they expect that the adapter supports class I2C_CLASS_HWMON. This patch adds functionality to allow platforms to set the class and pass it as platform_data to the i2c-pxa driver. Sample usage in platform code: static struct i2c_pxa_platform_data my_i2c_platform_data = { .class = I2C_CLASS_HWMON }; static void __init my_platform_init(void) { (void) platform_add_devices(devices, ARRAY_SIZE(devices)); pxa_set_i2c_info(&my_i2c_platform_data); } Signed-off-by: Matej Kenda <matej.kenda@hermes-softlab.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | * [ARM] 4278/1: configure pxa27x I2C SCL as "input"Guennadi Liakhovetski2007-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | It has been reported by Julian Deng that configuring the pxa27x i2c SCL line as output generates a short negative pulse on it during the call to pxa_gpio_mode(GPIO117_I2CSCL_MD); as it first switches it to output and then configures it for the alternate function. The SCL line is in fact bidirectional and can also be configured as 117 | GPIO_ALT_FN_1_IN, in which case the pulse is not generated. This is exactly what this patch does.

| * | [PATCH] gpio_direction_output() needs an initial valueDavid Brownell2007-03-16
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

This implementation has no real code because ixp4xx doesn't use vbus - only vbus uses all these gpio functions (and because ixp4xx misses any function which converts number of gpio pin into it's irq).

Both chips have the same "Serial Audio Controller" registers although the SA1111 one is never expected to be used in preference to the PXA25x one. So let's disable the SA1111 defines whenever compilation is for a PXA architecture and make the PXA defines always defined. This removes a bunch of "already defined" warnings as well since the current hack to prevent them depended on include ordering which wasn't always right. While at it, clean up the SA1111 defines allowing to get rid of the __CCREG() macro. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [PATCH] spi: stabilize PIO mode transfers on PXA2xx systemsStephen Street2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stabilize PIO mode transfers against a range of word sizes and FIFO thresholds and fixes word size setup/override issues. 1) 16 and 32 bit DMA/PIO transfers broken due to timing differences. 2) Potential for bad transfer counts due to transfer size assumptions. 3) Setup function broken is multiple ways. 4) Per transfer bit_per_word changes break DMA setup in pump_tranfers. 5) False positive timeout are not errors. 6) Changes in pxa2xx_spi_chip not effective in calls to setup. 7) Timeout scaling wrong for PXA255 NSSP. 8) Driver leaks memory while busy during unloading. Known issues: SPI_CS_HIGH and SPI_LSB_FIRST settings in struct spi_device are not handled. Testing: This patch has been test against the "random length, random bits/word, random data (verified on loopback) and stepped baud rate by octaves (3.6MHz to 115kHz)" test. It is robust in PIO mode, using any combination of tx and rx thresholds, and also in DMA mode (which internally computes the thresholds). Much thanks to Ned Forrester for exhaustive reviews, fixes and testing. The driver is substantially better for his efforts.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most architectures have fairly simple discontiguous memory - a simple set of successive regions each containing some memory. These can be described simply as a log2 of their maximum size, along with the base address of the first region and the number of regions. The base address is already described by PHYS_PFN_OFFSET, and the number of regions via the MAX_NUMNODES and the number of online nodes. If we then supply the log2 of their maximum size, all the other discontigmem macros can move into generic code. There is one exception: lh7a40x seems to have a more complicated setup; this is left alone. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 3848/1: pxafb: Add option of fixing video modes and spitz QVGA mode ↵Richard Purdie2006-10-02
| | | | | | | | | | | | | | | | | | | support Add the ability to have pxafb use only certain fixed video modes (selected on a per platform basis). This is useful on production hardware such as the Zaurus cxx00 models where the valid modes are known in advance and any other modes could result in hardware damage. Following this, add support for the cxx00 QVGA mode. Mode information is passed to the lcd_power call to allowing the panel drivers to configure the display hardware accordingly (corgi_lcd already contains the functionality for the cxx00 panel). This mirrors the setup already used by w100fb. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* USB: pxa2xx_udc understands GPIO based VBUS sensingDavid Brownell2006-09-27
| | | | | | | | | | | | | | | | This updates the PXA 25x UDC board-independent infrastructure for VBUS sensing and the D+ pullup. The original code evolved from rather bizarre support on Intel's "Lubbock" reference hardware, so that on more sensible hardware it doesn't work as well as it could/should. The change is just to teach the UDC driver how to use built-in PXA GPIO pins directly. This reduces the amount of board-specfic object code needed, and enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one. With VBUS sensing, the UDC is unclocked until a host is actually connected. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
