This patch series primarily adds the powerdown-gpios support
for the IS31FL32xx controller.It also includes a fix and
dt-bindings updates derived from previous attempts [1].

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.
