Subject: [PATCH v1 1/2] dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280
Date: Tue, 31 Aug 2021 16:06:41 +0530	[thread overview]
Message-ID: <1630406202-3919-1-git-send-email-tdas@codeaurora.org> (raw)

The LPASS(Low Power Audio Subsystem) clock provider have a bunch of generic
properties that are needed in a device tree. Add the LPASS clock IDs for
LPASS PIL client to request for the clocks.
