2023-09-13	clk: qcom: clk-hfpll: Configure l_val in init when required	Adam Skladowski	1	-0/+4
	Add support for pre-configuring default frequency multiplier, this appears to be required on some platforms like MSM8976. Without configuring L_VAL device reboots when trying to bring PLL up.

2023-03-14	clk: qcom: clk-hfpll: switch to .determine_rate	Luca Weiss	1	-7/+7
	.determine_rate is meant to replace .round_rate. The former comes with a benefit which is especially relevant on 32-bit systems: since .determine_rate uses an "unsigned long" (compared to a "signed long" which is used by .round_rate) the maximum value on 32-bit systems increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz).

2022-06-27	clk: qcom: clk-hfpll: use poll_timeout macro	Ansuel Smith	1	-6/+9
	Use regmap_read_poll_timeout macro instead of do-while structure to tidy things up. Also set a timeout to prevent any sort of system stall.

2019-12-24	clk: let init callback return an error code	Jerome Brunet	1	-2/+4
	If the init callback is allowed to request resources, it needs a return value to report the outcome of such a request.

2018-10-17	clk: qcom: Add support for High-Frequency PLLs (HFPLLs)	Stephen Boyd	1	-0/+244
	HFPLLs are the main frequency source for Krait CPU clocks. Add support for changing the rate of these PLLs.
