Linus Torvalds 36001a2fa6 The clk core gains a new set of APIs that allow drivers to both acquire clks
and prepare and enable them at the same time. This also comes with devm support
 so that drivers can make a single call to get and prepare and enable the clk
 and have that all undone when their driver is removed. Many folks have
 requested this feature over the years, but we've had disagreements about how to
 implement it and if it was worthwhile to encourage drivers to use such an API.
 Now it's here, so let's see how it goes. I hope that by introducing this API we
 can identify drivers that would benefit from further consolidation of clk API
 usage, possibly by moving such logic to the bus layer and out of drivers
 altogether.
 
 Outside of that major API update, we have the usual collection of driver
 updates. A few new SoCs are supported, mostly Qualcomm and Renesas this time
 around. Then we have the long tail of non-critical fixes and minor feature
 additions to various clk drivers. And finally more clk provider migration to
 struct clk_parent_data, reducing boot times in the process.
 
 Core:
  - devm helpers for clk_get() + clk_prepare() and clk_enable()
 
 New Drivers:
  - Support for the camera clock controller in Qualcomm SM8450 and
    the display and gpu clock controllers in Qualcomm SM8350
  - Add support for the Renesas RZ/Five SoC
 
 Updates:
  - Various fixes, new clocks and USB GDSCs are introduced for Qualcomm IPQ8074
  - Fixes to Qualcomm MSM8939 for issues introduced by inheriting the MSM8916
    GCC driver
  - Support for a new type of voteable GDSCs used by Qualcomm SC8280XP PCIe
    GDSCs
  - Qualcomm SC8280XP pipe clocks transitioned to the new phy-mux implementation
  - Qualcomm MSM8996 GCC, RPM clock driver and some clocks in MSM8994 GCC are
    migrated to use clk_parent_data
  - Corrected the topology for Titan (camera) GDSCs on Qualcomm SDM845 and
    SM8250
  - Qualcomm MSM8916 gains more possible frequencies for its GP clocks.
  - The GCC and tsens handling on Qualcomm MSM8960 is reworked to mimic the
    design in IPQ8074 to allow the GCC driver to probe earlier.
  - The regulator based mmcx supply for Qualcomm dispcc and videocc is dropped,
    as the only upstream target that adapted this interface was transitioned
    several kernel versions ago
  - Qualcomm GDSCs found to be enabled at boot will now reflect in the enable
    count of the supply, as was done with the regulator supplies previously
  - Correct adc1, nic_media and edma1's parents for NXP i.MX93
  - rdiv, mfd values, the return rate in recalc_rate and add more frequencies in
    the table for fracn-gppll on i.MX
  - Remove Allwinner workaround logic/compatible in fixed factor code
  - MediaTek clk driver cleanups
  - Add reset support to more MediaTek clk drivers
  - deduplicate Allwinner ccu_clks arrays
  - Allwinner H6 GPU DFS support
  - Adjust Allwinner Kconfig to limit choice
  - Fix initconst confusion on Renesas R-Car Gen4
  - Add GPT/POEG (PWM) clocks and resets on Renesas RZ/G2L
  - Add PFC and WDT clocks and resets on Renesas RZ/V2M
  - Add thermal, SDHI, Z (CPU core), PCIe, and HSCIF (serial) clocks on
    Renesas R-Car S4-8
