Currently gcc-msm8960 driver manually creates tsens platform device manually. It would be better to follow IPQ8064 approach, where tsens device is defined as gcc's child device in the device tree. If nothing else, it removes gcc's dependency on QFPROM, thus allowing clock controller to be probed earlier. Don't create it in case there are available child nodes (tsens) inside the gcc's device tree node. Signed-off-by:

Split tsens properties to the child node of the gcc. This follows the lead of ipq8064 (which also uses a separate node for tsens) and makes device tree closer to other platforms, where tsens is a completely separate device. Signed-off-by:

MSM8960 shares the design (and the driver) of the global clock controller with APQ8064. Move it from clock/qcom,gcc-other.yaml to clock/qcom,gcc-apq8064.yaml. As the example in gcc-other.yaml was using qcom,gcc-msm8960 compat string, change it to qcom,gcc-msm8974. Reviewed-by:

msm8916 has (at least) 6 "General Purpose" clocks that can be muxed to SoC pins. These clocks are: GP_CLK{0, 1} : GPIO_{31, 32} (Belongs to CAMSS according to Linux) GP_CLK_{1-3}{A, B} : GPIO_{49-51, 97, 12, 13} (Belongs to GCC itself) GP_MN : GPIO_110 (Doesn't seem to be described in gcc, ignored in this patch) Those clocks may be used as e.g. PWM sources for external peripherals. Add more frequencies to the table for those clocks so it's possible for arbitrary peripherals to make use of them. Reviewed-by:Nikita Travkin <nikita@trvn.ru> Signed-off-by:

UBI32 Huayra PLL fails to lock in 5 us in some SoC silicon and thus it will cause the wait_for_pll() to timeout and thus return the error indicating that the PLL failed to lock. This is bug in Huayra PLL HW for which SW workaround is to set bit 26 of TEST_CTL register. This is ported from the QCA 5.4 based downstream kernel.

Like in IPQ6018 the NSS related Alpha PLL-s require initial configuration to work. So, obtain the regmap that is required for the Alpha PLL configuration and thus utilize the qcom_cc_really_probe() as we already have the regmap. Then utilize the Alpha PLL configs from the downstream QCA 5.4 based kernel to configure them. This fixes the UBI32 and NSS crypto PLL-s failing to get enabled by the kernel.

Use the new phy-mux clock implementation for the PCIe pipe clock muxes so that the pipe clock source is set to the QMP PHY PLL when the downstream pipe clock is enabled and restored to the always-on XO when it is again disabled. This is needed to prevent the corresponding GDSC from hanging when enabling or disabling the PCIe power domain, something which requires a ticking source. Signed-off-by:
