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 Removed 2 patches from V1 as they have been merged * dt-bindings: cpufreq: qcom-cpufreq-nvmem: document IPQ5332 * dt-bindings: cpufreq: qcom-cpufreq-nvmem: document IPQ9574 v4: Included a patch to fix 'kernel test robot' build error -- https://lore.kernel.org/r/202310181650.g8THtfsm-lkp@intel.com/ v5: Use devm_clk_notifier_register Merge IPQ53xx and IPQ95xx cases with APQ8096 for speed bin selection Add reviewed by tags v6: Except these 2 patches, rest have been merged...
