Subject: [PATCH v2 2/3] dt-bindings: clock: Add YAML schemas for the QCOM Camera clock bindings.
Date: Tue, 13 Oct 2020 22:41:49 +0530
Message-ID: <1602609110-11504-3-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1602609110-11504-1-git-send-email-tdas@codeaurora.org>

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

Add clock ids for camera clocks which are required to bring the camera
subsystem out of reset.
