From Bryan Wu <bryan.wu@canonical.com>: 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. 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 * 'for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds: ARM: use new LEDS CPU trigger stub to replace old one ARM: mach-sa1100: retire custom LED code ARM: mach-omap1: retire custom LED code ARM: mach-pnx4008: remove including old leds event API header file ARM: plat-samsung: remove including old leds event API header file ARM: mach-pxa: retire custom LED code char: nwflash: remove old led event code ARM: mach-footbridge: retire custom LED code ARM: mach-ebsa110: retire custom LED code ARM: mach-clps711x: retire custom LED code of P720T machine ARM: mach-integrator: retire custom LED code ARM: mach-integrator: move CM_CTRL to header file for accessing by other functions ARM: mach-orion5x: convert custom LED code to gpio_led and LED CPU trigger ARM: mach-shark: retire custom LED code ARM: mach-ks8695: remove leds driver, since nobody use it ARM: mach-realview and mach-versatile: retire custom LED code ARM: at91: convert old leds drivers to gpio_led and led_trigger drivers led-triggers: create a trigger for CPU activity Conflicts: arch/arm/mach-clps711x/p720t.c arch/arm/mach-sa1100/leds-cerf.c arch/arm/mach-sa1100/leds-lart.c Let's hope this is the last time we pull this and it doesn't cause more trouble. I have verified that version 10 causes no build warnings or errors any more, and the patches still look good. Signed-off-by: Arnd Bergmann <arnd@arndb.de> |
