Subject: [PATCH 4/6] dt-bindings: soc: qcom: convert non-smd RPM bindings to
dt-schema
Convert the non-SMD RPM node bindings to dt-schema, the regulators subnode
refers to regulators,yaml until we have the proper bindings.
Signed-off-by: Neil Armstrong <neil.armstrong@...aro.org>

+description: |
+ This driver is used to interface with the Resource Power Manager (RPM) found
+ in various Qualcomm platforms. The RPM allows each component in the system
