Patch 1 and patch 2 are based on a previous attempt [1]. The driver-related updates in patch 2 have already been merged. Patch 3 and Patch 4 add support for the powerdown-gpios property, which corresponds to the SDB pin of the IS31FL32xx series chips. This pin is used to enter and exit the hardware powerdown mode. Patch 5 fixes errors introduced by previous changes. It impacts the brightness control function of the IS31FL3236. Patch 6 resolves regression caused by prior changes, and fixes the 22kHz PWM output functionality for IS31FL3236A.
