Depends On: https://lore.kernel.org/lkml/20230913-gpll_cleanup-v2-6-c8ceb1a37680@quicinc.com/T/
This patch series aims to enable cpufreq for IPQ5332 and IPQ9574. For IPQ5332, a minor enhancement to Stromer Plus ops and a safe source switch is needed before cpu freq can be enabled.
These are also included in this series. Posting this as a single series. Please let me know if this is not correct, will split in the subsequent revisions.
Passed the following DT related validations make W=1 ARCH=arm64 -j16 DT_CHECKER_FLAGS='-v -m' dt_binding_check DT_SCHEMA_FILES=qcom make W=1 ARCH=arm64 -j16 CHECK_DTBS=y DT_SCHEMA_FILES=qcom dtbs_check
For IPQ5332: ~~~~~~~~~~~ * This patch series introduces stromer plus ops which builds on stromer ops and implements a different set_rate and determine_rate.
A different set_rate is needed since stromer plus PLLs do not support dynamic frequency scaling. To switch between frequencies, we have to shut down the PLL, configure the L and ALPHA values and turn on again. So introduce the separate set of ops for Stromer Plus PLL.
* Update ipq_pll_stromer_plus to use clk_alpha_pll_stromer_plus_ops instead of clk_alpha_pll_stromer_ops.
* Set 'l' value to a value that is supported on all SKUs.
* Provide safe source switch for a53pll
* Include IPQ5332 in cpufreq nvmem framework
* Add OPP details to device tree
For IPQ9574: ~~~~~~~~~~~ * Include IPQ9574 in cpufreq nvmem framework
* Add OPP details to device tree
