Subject: [PATCH v1 1/3] dt-bindings: clock: Add YAML schemas for the QCOM DISPCC clock bindings
Date: Fri, 15 Nov 2019 15:34:03 +0530	[thread overview]
Message-ID: <1573812245-23827-2-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1573812245-23827-1-git-send-email-tdas@codeaurora.org>

The DISPCC clock provider have a bunch of generic properties that
are needed in a device tree. Add a YAML schemas for those.

-Required properties :
-
-- compatible : shall contain "qcom,sdm845-dispcc"
-- reg : shall contain base register location and length.
-- #clock-cells : from common clock binding, shall contain 1.
-- #reset-cells : from common reset binding, shall contain 1.
-- #power-domain-cells : from generic power domain binding, shall contain 1.
