Convert the driver to parent data API. From the Documentation pll8_vote and pxo should be declared in the DTS so fw_name can be used instead of parent_names. .name is changed to the legacy pxo_board following how it's declared in other drivers. Signed-off-by:

Introduce (devm_)hw_register_mux_parent_data_table new API. We have basic support for clk_register_mux using parent_data but we lack any API to provide a custom parent_map. Add these 2 new API to correctly handle these special configuration instead of using the generic __(devm_)clk_hw_register_mux API. Signed-off-by:

Merge tag 'qcom-clk-for-6.1' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into clk-qcom Pull Qualcomm clk driver updates from Bjorn Andersson: This introduces display clock controllers are introduces for SM6115 and SM8450, and SC8280XP gains a GPU clock controller. MSM8909 and SM6375 gains global and SMD RPM clock controller drivers. The handling of GDSCs with PWRSTS_RET was fixed, to keep the GDSC on while powering down the parent supply. This solved retention issues during suspend of USB on sc7180/7280 and SC8280XP. SM6115 and QCM2260 are moved to reuse PLL configuration. SDM660 SDCC1 was moved to floor ops. Support for the APCS PLLs for IPQ8064, IPQ8074 and IPQ6018 was added/fixed. The MSM8996 CPU clocks was updated, with support for ACD clocks added. Support for SDM670 was added to the SDM845 Glbal clock controller and the RPMh clock controller driver. Transition to parent_data, parent_hws and use of ARRAY_SIZE() for num_parents was done for MSM8660, MSM8916, MSM8939, MSM8960 global clock controllers, IPQ8064 LPASS clock controller and MSM8960 multimedia clock controller. Support for per-reset defined delay of was introduced. * tag 'qcom-clk-for-6.1' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (93 commits) clk: qcom: gcc-msm8939: use ARRAY_SIZE instead of specifying num_parents clk: qcom: gcc-msm8939: use parent_hws where possible dt-bindings: clock: move qcom,gcc-msm8939 to qcom,gcc-msm8916.yaml clk: qcom: gcc-sm6350: Update the .pwrsts for usb gdscs clk: qcom: gcc-sc8280xp: use retention for USB power domains clk: qcom: gdsc: add missing error handling dt-bindings: clocks: qcom,gcc-sc8280xp: Fix typos clk: qcom: Add global clock controller driver for SM6375 dt-bindings: clock: add SM6375 QCOM global clock bindings clk: qcom: alpha: Add support for programming the PLL_FSM_LEGACY_MODE bit clk: qcom: gcc-sc7280: Update the .pwrsts for usb gdscs clk: qcom: gcc-sc7180: Update the .pwrsts for usb gdsc clk: qcom: gdsc: Fix the handling of PWRSTS_RET support clk: qcom: Add SC8280XP GPU clock controller dt-bindings: clock: Add Qualcomm SC8280XP GPU binding clk: qcom: smd: Add SM6375 clocks dt-bindings: clock: qcom: rpmcc: Add BIMC_FREQ_LOG dt-bindings: clock: qcom,rpmcc: Add compatible for SM6375 clk: qcom: rpmhcc: add sdm670 clocks dt-bindings: clock: add rpmhcc bindings for sdm670 ...

The USB controllers on sm6350 do not retain the state when the system goes into low power state and the GDSCs are turned off. This can be observed by the USB connection not coming back alive after putting the device into suspend, essentially breaking USB. Fix this by updating the .pwrsts for the USB GDSCs so they only transition to retention state in low power. Cc: Rajendra Nayak <quic_rjendra@quicinc.com> Signed-off-by:

Since commit d3997239 ("clk: qcom: gdsc: Fix the handling of PWRSTS_RET support) retention mode can be used on sc8280xp to maintain state during suspend instead of leaving the domain always on. This is needed to eventually allow the parent CX domain to be powered down during suspend. Signed-off-by:

Since commit 7eb231c3 ("PM / Domains: Convert pm_genpd_init() to return an error code") pm_genpd_init() can return an error which the caller must handle. The current error handling was also incomplete as the runtime PM and regulator use counts were not balanced in all error paths. Add the missing error handling to the GDSC initialisation to avoid continuing as if nothing happened on errors. Signed-off-by:

The USB controllers on sc7280 do not retain the state when the system goes into low power state and the GDSCs are turned off. This results in the controllers reinitializing and re-enumerating all the connected devices (resulting in additional delay while coming out of suspend) Fix this by updating the .pwrsts for the USB GDSCs so they only transition to retention state in low power. Since sc7280 only supports cx (parent of usb gdscs) Retention, there are no cxcs offsets mentioned in order to support the Retention state. Signed-off-by:

GDSCs cannot be transitioned into a Retention state in SW. When either the RETAIN_MEM bit, or both the RETAIN_MEM and RETAIN_PERIPH bits are set, and the GDSC is left ON, the HW takes care of retaining the memory/logic for the domain when the parent domain transitions to power collapse/power off state. On some platforms where the parent domains lowest power state itself is Retention, just leaving the GDSC in ON (without any RETAIN_MEM/RETAIN_PERIPH bits being set) will also transition it to Retention. The existing logic handling the PWRSTS_RET seems to set the RETAIN_MEM/RETAIN_PERIPH bits if the cxcs offsets are specified but then explicitly turns the GDSC OFF as part of _gdsc_disable(). Fix that by leaving the GDSC in ON state. Signed-off-by:
