Subject: [PATCH] pwm: brcmstb: Utilize appropriate clock APIs in suspend/resume
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: e9bc4411548aaa738905d37851a0146c16b3bb21
Patch-mainline: v6.7-rc1
References: git-fixes

The suspend/resume functions currently utilize
clk_disable()/clk_enable() respectively which may be no-ops with certain
clock providers such as SCMI. Fix this to use clk_disable_unprepare()
and clk_prepare_enable() respectively as we should.
