We are using msm kernel as base not SODP ports. https://android.googlesource.com/kernel/msm/+/android-lego-6.0.1_r0.2/drivers/clk/qcom/clock-cpu-8976.c https://android.googlesource.com/kernel/msm.git/+/android-msm-lego-3.10-marshmallow-dr/arch/arm/boot/dts/qcom/msm8976.dtsi#349 > [...] >> static const struct of_device_id qcom_hfpll_match_table[] = { >> { .compatible = "qcom,hfpll", &hdata }, >> + { .compatible = "qcom,msm8976-hfpll-a53", &msm8976_a53 }, >> + { .compatible = "qcom,msm8976-hfpll-a72", &msm8976_a72 }, >> + { .compatible = "qcom,msm8976-hfpll-cci", &msm8976_cci }, > .data = is missing > > Konrad Seems like i took "inspiration" from also not great code, albeit it does work somehow when printing inside init, will fix in v3 Thanks Angelo/Konrad

Add PLL configuration for MSM8976 SoC, this SoC offers 3 HFPLL. Small cluster offers two presets for 652-902Mhz range and 902Mhz-1.47Ghz. For simplicity only add second range as smaller frequencies can be obtained via apcs divider or safe parent this also saves us a hassle of reconfiguring VCO bit and config_val. A72 and CCI cluster only use single frequency range with their outputs/post_dividers/vco_bits being static.
