In case of all pipe clocks, there is a QMP PHY clock that is feeding them. If, for whatever reason, the clock from the PHY is not enabled, halt bit will not get set, and the clock controller driver will assume the clock is stuck in a specific state. The way this is supposed to be properly fixed is to defer the checking of the halt bit until after the PHY clock has been initialized, but doing so complicates the clock controller driver. In fact, since these pipe clocks are consumed by the PHY, while the PHY is also the one providing the source, if clock gets stuck, the PHY driver would be to blame. So instead of checking the halt bit in here, just skip it and assume the PHY driver is handling the source clock correctly.

The GPU clocks/GDSCs have been marked critical from the clock driver but the GPU driver votes on these resources as per the HW requirement. In the case where these clocks & GDSCs are left enabled, would have power impact and also cause GPU stability/corruptions.

Commit 8cab0336 ("clk: qcom: Add QCM2290 GPU clock controller driver") adds the config CLK_QCM2290_GPUCC, which intends to select the support for the QCM2290 Global Clock Controller. It however selects the non-existing config CLK_QCM2290_GCC, whereas the config for the QCM2290 Global Clock Controller is named QCM_GCC_2290. Adjust the config to the intended one. Signed-off-by:

Commit 134b55b7 ("clk: qcom: support Huayra type Alpha PLL") introduced an entry to the alpha offsets array, but diving into QCM2290 downstream and some documentation, it turned out that the name Huayra apparently has been used quite liberally across many chips, even with noticeably different hardware. Introduce another set of offsets and a new configure function for the Huayra PLL found on QCM2290. This is required e.g. for the consumers of GPUCC_PLL0 to properly start. Reviewed-by:

The clock controller driver of qca8386/qca8084 is registered as the MDIO device, the hardware register is accessed by MDIO bus that is normally used to access general PHY device, which is different from the current existed qcom clock controller drivers using ioremap to access hardware clock registers, nsscc-qca8k is accessed via an MDIO bus. MDIO bus is commonly utilized by both qca8386/qca8084 and other PHY devices, so the mutex lock mdio_bus->mdio_lock should be used instead of using the mutex lock of remap. To access the hardware clock registers of qca8386/qca8084, there is a special MDIO frame sequence, which needs to be sent to the device. Enable the reference clock before resetting the clock controller, the reference clock rate is fixed to 50MHZ. Reviewed-by:

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. Reviewed-by:
