If anyone has any objections, please let me know. ------------------ From: Florian Fainelli [ Upstream commit e9bc4411548aaa738905d37851a0146c16b3bb21 ] 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.
