[PATCH v1 1/2] dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280

From: Taniya Das
Date: Tue Aug 31 2021 - 06:38:42 EST


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.
