Subject: dt-bindings: clock: Add "qcom,adsp-pil-mode" property
X-Git-Tag: v6.1-rc5~153^2~7^6~4^2~79^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7afdf3afff6f434a2c0b5d55e03ae14d7992d48c;p=platform%2Fkernel%2Flinux-starfive.git

dt-bindings: clock: Add "qcom,adsp-pil-mode" property

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.
