* firmware_class: Rework usermodehelper checkRafael J. Wysocki2012-03-28
| | | | | | | | | | | | | | | | Instead of two functions, read_lock_usermodehelper() and usermodehelper_is_disabled(), used in combination, introduce usermodehelper_read_trylock() that will only return with umhelper_sem held if usermodehelper_disabled is unset (and will return -EAGAIN otherwise) and make _request_firmware() use it. Rename read_unlock_usermodehelper() to usermodehelper_read_unlock() to follow the naming convention of the new function. Signed-off-by: Rafael J.

* Merge branch 'pm-runtime' into linux-nextRafael J. Wysocki2012-03-28
|\ | | | | | | | | * pm-runtime: PM / Runtime: don't forget to wake up waitqueue on failure
| * PM / Runtime: don't forget to wake up waitqueue on failureAlan Stern2012-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1535) fixes a bug in the runtime PM core. When a runtime suspend attempt completes, whether successfully or not, the device's power.wait_queue is supposed to be signalled. But this doesn't happen in the failure pathway of rpm_suspend() when another autosuspend attempt is rescheduled. As a result, a task can get stuck indefinitely on the wait queue (I have seen this happen in testing). The patch fixes the problem by moving the wake_up_all() call up near the start of the failure code.

This patch introduces basic clock types for the above-mentioned hardware which share some common characteristics. Based on original work by Jeremy Kerr and contribution by Jamie Iles. Dividers and multiplexor clocks originally contributed by Richard Zhao & Sascha Hauer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The common clock framework defines a common struct clk useful across most platforms as well as an implementation of the clk api that drivers can use safely for managing clocks. The net result is consolidation of many different struct clk definitions and platform-specific clock framework implementations. This patch introduces the common struct clk, struct clk_ops and an implementation of the well-known clock api in include/clk/clk.h. Platforms may define their own hardware-specific clock structure and their own clock operation callbacks, so long as it wraps an instance of struct clk_hw. See Documentation/clk.txt for more details. This patch is based on the work of Jeremy Kerr, which in turn was based on the work of Ben Herrenschmidt.

Currently the following devices are supported via the devicetree: - VIC interrupts - PL011 UART - PL061 GPIO - Synopsys DW I2C - Synopsys DW ethernet Other peripheral devices (e.g. SMI flash, FSMC NAND flash etc) will follow in later patches. Only the spear600-evb is currently supported. Other SPEAr600 based boards will follow later. Since the current mainline SPEAr600 code only supports the SPEAr600 evaluation board, with nearly zero peripheral devices (only UART and GPIO), it makes sense to switch over to DT based configuration completely now. So this patch also removes all non-DT stuff, mainly platform device data. The files spear600.c and spear600_evb.c are removed completely.

This will not do much by itself because the device from the device tree are not matched by any device driver until they are converted as well. The next step is to move over one device at a time to actually be used from the device tree instead of the hardcoded device using auxdata to pass the correct platform_data.
