Patch 1 refactors the power on and power off sequences into separate functions in preparation for subsequent patches. Patch 2 adds an optional GPIO to enable a backlight. This patch only includes the field within the platform data so that it can be properly setup before actually being put to use. Patches 3 to 7 convert all users of the pwm-backlight driver to use the new field. For most of them, this just initializes the field to -1, marking the field as unused. Patch 8 uses the new field within the pwm-backlight driver and at the same time allows it to be parsed from device tree. Patch 9 implements support for an optional power supply. This relies on the regulator core to return a dummy regulator when no supply has been otherwise setup so the driver doesn't have to handle that specially nor require all users to be updated. Patch 10 adds a way to keep a backlight turned off at boot. This is useful when hooking up a backlight with a subsystem such as DRM which has more explicit semantics as to when a backlight should be turned on. Due to the dependencies within the series, I propose to take all these patches through the PWM tree, so I'll need acks from OMAP, PXA, Samsung, shmobile and Unicore32 maintainers.
