Merge tag 'pwm/for-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm changes from Thierry Reding:
"Mostly bug fixes and clean up. There is a new driver, which is
actually moving a custom PWM driver from drivers/misc.
The majority of the patches are enhancements to the device tree
support in the pwm-backlight driver. Backlights can now additionally
be powered using a regulator and enabled using a GPIO in addition to
just the PWM input"
