[PATCH v2 3/8] leds: syscon: Support 'reg' in addition to 'offset' for register address

From: Rob Herring
Date: Mon Sep 13 2021 - 15:28:32 EST


The register-bit-led binding now also supports 'reg' in addition to
'offset' for the register address. Add support to the driver to get the
address from 'reg'.
