Subject: [PATCH 5/6] dt-bindings: regulators: convert non-smd RPM Regulators bindings to dt-schema
Date: Thu, 06 Oct 2022 09:58:02 +0000	[thread overview]
Message-ID: <20221005-mdm9615-pinctrl-yaml-v1-5-0cbc006e2a30@linaro.org> (raw)
In-Reply-To: <20221005-mdm9615-pinctrl-yaml-v1-0-0cbc006e2a30@linaro.org>

Convert the non-SMD Regulators  bindings to dt-schema and remove the
old text based bindings now we have migrated all the content.

-Qualcomm Resource Power Manager (RPM)
-
-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 to vote
-for state of the system resources, such as clocks, regulators and bus
-frequencies.
-
-Please refer to soc/qcom/qcom,ipc-rpm.yaml
-
-= SUBNODES
-
-The RPM exposes resources to its subnodes. The below bindings specify the set
-of valid subnodes that can operate on these resources.
-
-== Regulators
-
-Regulator nodes are identified by their compatible:
