* Reservations: fix time-tracking of table-driven reservationsBjoern Brandenburg2014-11-03
| | | | | | Keep track of the current slot and major cycle explicitly to avoid ambiguity when the budget charging is delayed into the next major cycle due to a late interrupt or other sources of delay.
* Reservations: priority should be a lt_tBjoern Brandenburg2014-11-03
| | | | | | | Rationale: the internal priority point representation is of type lt_t (64 bits), so to enable userspace to specify priorities below (=after) EDF priority points, we need to allow userspace to specify values larger than 2^32.
* Reservations: keep track of consumed budgetBjoern Brandenburg2014-11-03
| | | | This can be a useful stat for userspace.
* Move 'reservation' field from task_client to generic reservation_clientBjoern Brandenburg2014-11-03
| | | | | | This makes it a lot easier to write generic code for thread arrival / thread departure in plugins with multiple types of reservation clients.
* Switch table-driven reservations to use table-driven budgetBjoern Brandenburg2014-11-03
| | | | | Instead of counting how much budget has been consumed, determine budget based on actual time slots.

* Integrate preemption state machine with Linux schedulerBjoern Brandenburg2014-10-21
| | | | Track when a processor is going to schedule "soon".
* Record LITMUS^RT timestamp in ftrace recordsGlenn Elliott2014-10-21
| | | | | Patch updates ftrace.h to record a litmus_clock() time stamp in ftrace records.
* Add LITMUS^RT core implementationBjoern Brandenburg2014-10-21
| | | | | | | | | | | | | This patch adds the core of LITMUS^RT: - library functionality (heaps, rt_domain, prioritization, etc.) - budget enforcement logic - job management - system call backends - virtual devices (control page, etc.) - scheduler plugin API (and dummy plugin) This code compiles, but is not yet integrated with the rest of Linux.
* Add object descriptor table to Linux's task_structBjoern Brandenburg2014-10-21
| | | | | This table is similar to a file descriptor table. It keeps track of which "objects" (locks) a real-time task holds a handle to.
* Add tracepoint supportBjoern Brandenburg2014-10-21
| | | | | | | This patch integrates LITMUS^RT's sched_trace_XXX() macros with Linux's notion of tracepoints. This is useful to visualize schedules in kernel shark and similar tools. Historically, LITMUS^RT's sched_trace predates Linux's tracepoint infrastructure.
* Add schedule tracing supportBjoern Brandenburg2014-10-21
| | | | | | This patch introduces the sched_trace infrastructure, which in principle allows tracing the generated schedule. However, this patch does not yet integrate the callbacks with the kernel.
* Introduce main LITMUS^RT headerBjoern Brandenburg2014-10-21
| | | | | This patch adds a basic litmus/litmus.h, which is required for basic LITMUS^RT infrastructure to compile.
* Extend task_struct with rt_paramBjoern Brandenburg2014-10-21
| | | | This patch adds the PCB extensions required for LITMUS^RT.
* Add hrtimer_start_on() supportFelipe Cerqueira2014-10-21
| | | | | | This patch adds hrtimer_start_on(), which allows arming timers on remote CPUs. This is needed to avoided timer interrupts on "shielded" CPUs and is also useful for implementing semi-partitioned schedulers.
* Add TRACE() debug tracing supportBjoern Brandenburg2014-10-21
| | | | This patch adds the infrastructure for the TRACE() debug macro.
* Add object list to inodesBjoern Brandenburg2014-10-21
| | | | | | | This patch adds a list of arbitrary objects to inodes. This is used by Linux's locking API to attach lock objects to inodes (which represent namespaces in Linux's locking API).
* Integrate ft_irq_fired() with LinuxBjoern Brandenburg2014-10-21
| | | | | This patch hooks up Feather-Trace's ft_irq_fired() handler with Linux's interrupt handling infrastructure.
* Feather-Trace: add LITMUS^RT overhead tracing infrastructureBjoern Brandenburg2014-10-21
| | | | | This patch adds the main infrastructure for tracing overheads in LITMUS^RT. It does not yet introduce any tracepoints into the kernel.
* Feather-Trace: add generic ftdev device driverBjoern Brandenburg2014-10-21
| | | | | This patch adds the ftdev device driver, which is used to export samples collected with Feather-Trace to userspace.
* Feather-Trace: add platform independent implementationBjoern Brandenburg2014-10-21
| | | | | This patch adds the simple fallback implementation and creates dummy hooks in the x86 and ARM Kconfig files.
* ENGR00323682 MMC: Fixed boot_config overwritten by switch partitionYe.Li2014-07-21
| | | | | | | | | | In MMC driver, two variables: boot_config and part_config are used to keep eCSD(179) PARTITION_CONFIG. The part_config is not updated when set new boot_config, which causes the eCSD(179) is overwritten by any following partition switching, so the new boot_config is lost.

* ENGR00322272-1: ARM: imx6sx: hide the buggy ldb_di_sel mux from clk APIShawn Guo2014-07-11
| | | | | | | | | | | | | | | | This is a smilar change for imx6sx clock tree as what we did for imx6q with commit 0bec46131d88 (ENGR00318063-8: ARM: imx6q: hide buggy ldb_di_sel from clk API). As the valid procedure of switching ldb_di_sel on imx6sx is not available yet, we hide this buggy mux by looking at the parent selection done by bootloader and register it statically to clock framework, so that switching this buggy mux becomes impossible. Also, since the bit width of ldb_di_sels is 3, we add two "dummy" entries for ldb_di_sels to avoid out-of-bounds error. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

* usb: gadget: udc-core: move sysfs_notify() to a workqueueFelipe Balbi2014-06-26
| | | | | | | | | | | | | | | | usb_gadget_set_state() will call sysfs_notify() which might sleep. Some users might want to call usb_gadget_set_state() from the very IRQ handler which actually changes the gadget state. Instead of having every UDC driver add their own workqueue for such a simple notification, we're adding it generically to our struct usb_gadget, so the details are hidden from all UDC drivers.

* drivers: usb: udc-core: add deferred bind for gadget driverRobert Baldyga2014-06-26
| | | | | | | | | | | | | | | | This patch adds support for deferred gadget driver bind as a remedy for situation when UDC drivers and gadget drivers are builded into the kernel, and gadget driver is loaded as first. Till now, in that case gadget driver loading failed with "No such device" and gadget driver didn't start. Now gadget drivers are added to driver_list and binded later, when UDC drivers will register in udc-core.

* ENGR00318063-9: clk: do not allow parent switching with another mux being childShawn Guo2014-06-25
| | | | | | | | | | | | | When switching parent clock with another basic mux clock being its child, a glitch might be generated and propagated to downstream clocks through this child mux. The patch adds a flag CLK_IS_BASIC_MUX to identify the basic mux clocks, and prohibit the parent switching when the clock itself is the parent of any basic mux clock. With this check, the parent switching of a clock has to happen before the child mux switches to this clock path. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
* ENGR00318063-3: ARM: imx6sx: fix ocram_sels mux settingShawn Guo2014-06-25
| | | | | | | | | | | | | | | The current imx6sx clock driver combines two mux clocks ocram_alt_sel and ocram_sel into one, while ocram_alt_sel is a glitchy mux and ocram_sel is a glitchless one. Fix it to match the clock tree in Reference Manual. One thing clk API clients need to take care is that clk_set_parent() can be called on glitchy ocram_alt_sel only when ocram_sel selects the other path, i.e. periph. Otherwise, a glitch could be generated on ocram_alt_sel and get propagated into the divider ocram_podf. In that case, ocram_podf gets locked up and ocram clock has no output.

* mmc: Allow setting slot index via devicetree aliasSascha Hauer2014-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As with gpio, uart and others, allow specifying the name_idx via the aliases-node in the devicetree. On embedded devices, there is often a combination of removable (e.g. SD card) and non-removable mmc devices (e.g. eMMC). Therefore the name_idx might change depending on - host of removable device - removable card present or not This makes it difficult to hard code the root device, if it is on the non-removable device. E.g. if SD card is present eMMC will be mmcblk1, if SD card is not present at boot, eMMC will be mmcblk0. If the aliases-node is not found, the driver will act as before. The original patch is from here: https://www.mail-archive.com/linux-mmc@vger.kernel.org/msg26472.html The patch requires additional alias_id fix or it won't work. Because according to function definition the max_idx parameter of idx_alloc is exclusive, so need add 1 or it will be unable to find the proper idx within an invalid range.

* ENGR00318773-4 mxc: asrc: Add driver suspend and resume to support MEGA FastNicolin Chen2014-06-19
| | | | | | | | | | For i.MX6 SoloX, there is a mode of the SoC to shutdown all power source of modules during system suspend and resume procedure. Thus, ASRC needs to save all the values of registers before the system suspend and restore them after the system resume.
