Pull PWM changes from Thierry Reding:
"A new driver has been added to support the PWM mode of the timer
counter blocks found on Atmel AT91 SoCs. The VT8500 driver now
supports changing the PWM signal polarity and the TI drivers (EHRPWM
and ECAP) gained suspend and resume functionality.User drivers can now query the core for whether access to a PWM device
will sleep (if the PWM chip is on a slow bus such as I2C or SPI).The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK
state in addition to the FB layer's blanking states.To round things off, a few fixes and cleanups are also included"

Add support to set polarity on PWM devices, allowing for inverted
duty cycles.Also update the binding document to #pwm-cells = to allow
passing the flags from devicetree.Signed-off-by: Tony Prisk

Correct operation for register writes is to perform a busy-wait
after writing the register. Currently the busy wait it performed
before, meaning subsequent register writes to bitfields may occur
before the previous field has been updated.Also, all registers are defined as 32-bit read/write. Change
pwm_busy_wait() to use readl rather than readb.Improve readability of code with defines for registers and bitfields.

This patch corrects a bug reported by Peter Vasil.
When all PWMs are disabled, PWM module may be disabled during
calls to pwm_config. This patch enables/disables the clock in
pwm_config to ensure the module is active before register read/
writes.Signed-off-by: Tony Prisk
