Depends On: https://lore.kernel.org/lkml/20230913-gpll_cleanup-v2-6-c8ceb1a37680@xxxxxxxxxxx/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 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 Varadarajan Narayanan (8): clk: qcom: clk-alpha-pll: introduce stromer plus ops clk: qcom: apss-ipq-pll: Use stromer plus ops for stromer plus pll clk: qcom: apss-ipq-pll: Fix 'l' value for ipq5332_pll_config clk: qcom: apss-ipq6018: ipq5332: add safe source switch for a53pll cpufreq: qti: Enable cpufreq for ipq53xx arm64: dts: qcom: ipq5332: populate the opp table based on the eFuse cpufreq: qti: Introduce cpufreq for ipq95xx arm64: dts: qcom: ipq9574: populate the opp table based on the eFuse arch/arm64/boot/dts/qcom/ipq5332.dtsi | 19 ++++++++++-- arch/arm64/boot/dts/qcom/ipq9574.dtsi | 21 ++++++++++++- drivers/clk/qcom/apss-ipq-pll.c | 4 +-- drivers/clk/qcom/apss-ipq6018.c | 53 +++++++++++++++++++++++++++++++- drivers/clk/qcom/clk-alpha-pll.c | 57 +++++++++++++++++++++++++++++++++++ drivers/clk/qcom/clk-alpha-pll.h | 1 + drivers/cpufreq/cpufreq-dt-platdev.c | 2 ++ drivers/cpufreq/qcom-cpufreq-nvmem.c | 16 ++++++++++ 8 files changed, 166 insertions(+), 7 deletions(-) -- 2.7.4
