Subject: [PATCH v10 00/18] Introduce a led trigger for CPU activity and consolidate LED driver in ARM
Based on Linus Walleij's ARM LED consolidation work, this patchset introduce a
new generic led trigger for CPU not only for ARM but also for others.
For enabling CPU idle event, CPU arch code should call ledtrig_cpu() stub to
trigger idle start or idle end event.
These patches convert old style LED driver in arch/arm to gpio_led or new led
driver interface. Against 3.5 release and build successfully for all the machines.
Test ledtrig-cpu driver on OMAP4 Panda board.
Please find these patches here:
git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds.git for-arm-soc
v9 --> v10
* fix compiling issue on versatile_defconfig reported by Russell King
* rebase to 3.5 kernel and move patches to new git tree
v8 --> v9:
* use mutex to replace rw_sema pointed out by Tim Gardner
* add a new struct led_trigger_cpu
* add lock_is_inited to record mutex lock initialization
v6 --> v7:
* add a patch to unify the led-trigger name
* fix some typo pointed
* use BUG_ON to detect CPU numbers during building stage
v5 --> v6:
* replace __get_cpu_var() to per_cpu()
* remove smp_processor_id() which is wrong with for_each_possible_cpu()
* test on real OMAP4 Panda board
* add comments about CPU hotplug in the CPU LED trigger driver
v4 --> v5:
* rebase all the patches on top of latest linux-next
* replace on_each_cpu() with for_each_possible_cpu()
* add some description of ledtrig_cpu() API
* remove old leds code from driver nwflash.c, which should use a new led trigger then
* this trigger driver can be built as module now
v3 --> v4:
* fix a typo pointed by Jochen Friedrich
* fix some building errors
* add Reviewed-by and Tested-by into patch log
v2 --> v3:
* almost rewrote the whole ledtrig-cpu driver, which is more simple
* every CPU will have a per-CPU trigger
* cpu trigger can be assigned to any leds
* fix a lockdep issue in led-trigger common code
* other fix according to review
v1 --> v2:
* remove select operations in Kconfig of every machines
* add back supporting of led in core module of mach-integrator
* solidate name scheme in ledtrig-cpu.c
* add comments of CPU_LED_* cpu led events
* fold patches of RealView and Versatile together
* add machine_is_ check during assabet led driver init
* add some Acked-by in patch logs
* remove code for simpad machine in machine-sa11000, since Jochen Friedrich
introduced gpiolib and gpio-led driver for simpad
* on Assabet and Netwinder machine, LED operations is reversed like:
setting bit means turn off leds
clearing bit means turn on leds
* add a new function to read CM_CTRL register for led driver
Bryan Wu (18):
