[PATCH RFT v2 2/4] dt-bindings: soc: qcom: smd-rpm: add qcom,glink-channels

From: Krzysztof Kozlowski
Date: Thu Sep 01 2022 - 05:34:29 EST


The Qualcomm Resource Power Manager (RPM) over SMD bindings contain
compatibles and description for RPM devices on two different
communication channels: SMD and GLINK. Except the difference in the
parent node, they use different properties for describing name of
channel qcom,smd-channels or qcom,glink-channels. The first one is
already present but second is missing:

qcom/sm6125-sony-xperia-seine-pdx201.dtb: rpm-requests: 'qcom,glink-channels' does not match any of the regexes: '^regulators(-[01])?$', 'pinctrl-[0-9]+'
