[PATCH V9 1/5] dt-bindings: clock: Add "qcom,adsp-pil-mode" property

From: Satya Priya
Date: Thu Sep 01 2022 - 00:18:04 EST


From: Taniya Das <quic_tdas@xxxxxxxxxxx>

When this property is set, the remoteproc is used to boot the
LPASS and therefore lpass_q6ss_ahbm_clk and lpass_q6ss_ahbs_clk
clocks would be used to bring LPASS out of reset and the rest of
the lpass clocks would be controlled directly by the remoteproc.

This is a cleanup done to handle overlap of regmap of
lpasscc and lpass_aon blocks.
