Subject: [PATCH 01/13] dt-bindings: leds: document Samsung S2M series PMIC
 flash LED device

Certain Samsung S2M series PMICs have a flash LED controller with
two LED channels, and with torch and flash control modes. Document the
devicetree schema for the device.

The initial driver introduced has support for S2MU005, add its
compatible as well.
