2018-10-17	clk: qcom: Add safe switch hook for krait mux clocks	Sricharan R	1	-0/+56
	When the Hfplls are reprogrammed during the rate change, the primary muxes which are sourced from the same hfpll for higher frequencies, needs to be switched to the 'safe secondary mux' as the parent for that small window. This is done by registering a clk notifier for the muxes and switching to the safe parent in the PRE_RATE_CHANGE notifier and back to the original parent in the POST_RATE_CHANGE notifier.

2018-10-17	clk: qcom: Add Krait clock controller driver	Stephen Boyd	1	-0/+341
	The Krait CPU clocks are made up of a primary mux and secondary mux for each CPU and the L2, controlled via cp15 accessors. For Kraits within KPSSv1 each secondary mux accepts a different aux source, but on KPSSv2 each secondary mux accepts the same aux source.
