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 3.1 mainline git tree and build successfully for
all the machines.
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
This patchset is based on patches from Jochen Friedrich for simpad:
