2018-10-18clk: s2mps11: Add used attribute to s2mps11_dt_matchNathan Chancellor
Clang warns after commit 8985167ecf57 ("clk: s2mps11: Fix matching when built as module and DT node contains compatible"): drivers/clk/clk-s2mps11.c:242:34: warning: variable 's2mps11_dt_match' is not needed and will not be emitted [-Wunneeded-internal-declaration] static const struct of_device_id s2mps11_dt_match[] = { ^ 1 warning generated. This warning happens when a variable is used in some construct that doesn't require a reference to that variable to be emitted in the symbol table; in this case, it's MODULE_DEVICE_TABLE, which only needs to hold the data of the variable, not the variable itself. $ nm -S drivers/clk/clk-s2mps11.o | rg s2mps11_dt_match 00000078 000003d4 R __mod_of__s2mps11_dt_match_device_table Normally, with device ID table variables, it means that the variable just needs to be tied to the device declaration at the bottom of the file, like s2mps11_clk_id: $ nm -S drivers/clk/clk-s2mps11.o | rg s2mps11_clk_id 00000000 00000078 R __mod_platform__s2mps11_clk_id_device_table 00000000 00000078 r s2mps11_clk_id However, because the comment above this deliberately doesn't want this variable added to .of_match_table, we need to mark s2mps11_dt_match as __used to silence this warning. This makes it clear to Clang that the variable is used for something, even if a reference to it isn't being emitted.

2018-10-17clk: qcom: Add safe switch hook for krait mux clocksSricharan R
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.

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.

The Krait clocks are made up of a series of muxes and a divider that choose between a fixed rate clock and dedicated HFPLLs for each CPU.
