This patch series primarily adds the shutdown-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 shutdown-gpios property, which corresponds to the SDB pin of the IS31FL32xx series chips. This pin is used to enter and exit the hardware shutdown mode. Patch 5 fixes errors introduced by previous changes. It impacts the brightness control function of the IS31FL3236.
