2025-03-05clk: qcom: gcc-sm8650: Do not turn off USB GDSCs during gdsc_disable()Neil Armstrong
With PWRSTS_OFF_ON, USB GDSCs are turned off during gdsc_disable(). This can happen during scenarios such as system suspend and breaks the resume of USB controller from suspend. So use PWRSTS_RET_ON to indicate the GDSC driver to not turn off the GDSCs during gdsc_disable() and allow the hardware to transition the GDSCs to retention when the parent domain enters low power state during system suspend.

2024-08-29clk: qcom: gcc-sm8650: Don't use shared clk_ops for QUPsNeil Armstrong
The QUPs aren't shared in a way that requires parking the RCG at an always on parent in case some other entity turns on the clk. The hardware is capable of setting a new frequency itself with the DFS mode, so parking is unnecessary. Furthermore, there aren't any GDSCs for these devices, so there isn't a possibility of the GDSC turning on the clks for housekeeping purposes. Like for the SM8550 GCC QUP clocks at [1], do not use shared clk_ops for QUPs.

2024-06-12clk: qcom: common: commonize qcom_cc_really_probeLuo Jie
The previous wrapper qcom_cc_really_probe takes the platform device as parameter, which is limited to platform driver. As for qca8k clock controller driver, which is registered as the MDIO device, which also follows the qcom clock framework. To commonize qcom_cc_really_probe, updating it to take the struct device as parameter, so that the qcom_cc_really_probe can be utilized by the previous platform device and the new added MDIO device. Also update the current clock controller drivers to take &pdev->dev as parameter when calling qcom_cc_really_probe.
