From adc1cd257234fddedb0166f0ed7ebdc989ab8d00 Mon Sep 17 00:00:00 2001 From: Jishnu Prakash Date: Wed, 2 Sep 2020 11:41:52 +0530 Subject: [PATCH] dt-bindings: backlight: Update qcom-spmi-wled DT bindings Add IIO properties io-channels and io-channel-names, which may be used for WLED to read QG channels. While at it, remove usage of PMIC revid.
