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" * tag 'pwm/for-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (30 commits) Documentation/pwm: Update supported SoC name for pwm-samsung pwm: samsung: Fix kernel warning while unexporting a channel MAINTAINERS: Move PWM subsystem tree to kernel.org Documentation/pwm: Fix trivial typos pwm-backlight: Remove unused variable pwm_backlight: avoid short blank screen while doing hibernation pwm-backlight: Fix brightness adjustment pwm: add ep93xx PWM support pwm-backlight: Allow for non-increasing brightness levels pwm-backlight: Add power supply support pwm-backlight: Use new enable_gpio field unicore32: Initialize PWM backlight enable_gpio field ARM: shmobile: Initialize PWM backlight enable_gpio field ARM: SAMSUNG: Initialize PWM backlight enable_gpio field ARM: pxa: Initialize PWM backlight enable_gpio field ARM: OMAP: Initialize PWM backlight enable_gpio field pwm-backlight: Add optional enable GPIO pwm-backlight: Track enable state pwm-backlight: Refactor backlight power on/off pwm-backlight: Improve readability ...
