Subject: [PATCH v3 1/2] dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280
Date: Mon, 24 Jan 2022 21:54:41 +0530	[thread overview]
Message-ID: <20220124162442.29497-2-tdas@codeaurora.org> (raw)
In-Reply-To: <20220124162442.29497-1-tdas@codeaurora.org>

The LPASS(Low Power Audio Subsystem) clock provider have a bunch of generic
properties that are needed in a device tree. Also add clock ids for
LPASS core clocks and audio clock IDs for LPASS client to request for
the clocks.
