clk: qcom: clk-hfpll: Configure l_val in init when required

2023-09-13T19:07:58Z

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.

clk: qcom: clk-hfpll: switch to .determine_rate

2023-03-13T23:38:24Z

.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).

clk: qcom: clk-hfpll: use poll_timeout macro

2022-06-27T20:41:37Z

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.

clk: let init callback return an error code

2019-12-24T02:53:13Z

If the init callback is allowed to request resources, it needs a return value to report the outcome of such a request.

clk: qcom: Add support for High-Frequency PLLs (HFPLLs)

2018-10-17T20:14:37Z

HFPLLs are the main frequency source for Krait CPU clocks. Add support for changing the rate of these PLLs. Signed-off-by: Stephen Boyd Signed-off-by: Sricharan R Tested-by: Craig Tatlor Signed-off-by: Stephen Boyd
