Linus Torvalds 1ec35eadc3 We have one small patch to the clk core this time around. It fixes a corner
case with the CLK_OPS_PARENT_ENABLE flag combined with clk_core_is_enabled()
 where it hangs the system. We'll simply assume the clk is disabled if the
 parent is disabled and the flag is set. Trying to turn on the parent to check
 the enable state of the clk runs into system hangs at boot. We let this bake in
 -next for a couple weeks to make sure there aren't any more issues because the
 last attempt to fix this ran into hangs and had to be reverted.
 
 Note: There were some more patches to the core framework around sync_state and
 disabling unused clks, but I asked for that to be reverted from the qcom PR
 because it isn't ready and we're still discussing the best solution on the
 list.
 
 Outside of the core clk framework, we have the usual collection of clk driver
 updates and support for new SoCs (which seems to never stop). The dirstat is
 dominated by Qualcomm because they added support for quite a few SoCs this time
 around and also migrated quite a few of their drivers to clk_parent_data. The
 other big diff is in the Mediatek clk drivers that saw a significant rework
 this cycle to similarly modernize the code, and we'll see that work continue in
 the next cycle as well. Nothing really jumps out as scary here, except that the
 significant churn in parent data descriptions can have typos that go unnoticed.
 More details below.
 
 Core:
  - Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled()
 
 New Drivers:
  - Add a new clk-gpr-mux clock type and use it on i.MX6Q to add ENET ref
    clocks

  - Support for many Qualcomm clk controllers:
    - QDU1000/QRU1000 global clock controller

    reference manual
  - Add ENET refclock mux support for i.MX6UL
  - Add support for USB host/device configuration on Renesas RZ/N1
  - Add PLL2 programming support, and CAN-FD clocks on Renesas R-Car V4H
  - Add D1 CAN bus gates and resets for Allwinner
  - Mark D1 CPUX clock as critical on Allwinner
  - Reuse D1 driver for Allwinner R528/T113

    sclk-div and cpu-dyn-div amlogic clock drivers
  - DDR clocks were marked as critical in the proper clock driver for each
    AT91 SoC such that drivers/memory/atmel-sdramc.c to be deleted
    in the next releases as it only does clock enablement
  - Patch to avoid compiling dt-compat.o for all AT91 SoCs as only some of
    them may use it
  - Support synchronous power_off requests in the qcom GDSC driver for proper
    GPU power collapse
  - Drop test clocks from various Qualcomm clk drivers
  - Update parent references to use clk_parent_data/clk_hw in various Qualcomm clk drivers
  - Fixes for the Qualcomm MSM8996 CPU clock controller
  - Transition Qualcomm MSM8974 GCC off the externally defined sleep_clk
  - Add GDSCs in the global clock controller for Qualcomm QCS404
  - The SDCC core clocks on Qualcomm SM6115 are moved to floor_ops
  - Programming of clk_dis_wait for GPU CX GDSC on Qualcomm SC7180 and SDM845 are
    moved to use the recently introduced properties in the GDSC struct
  - Qualcomm's RPMh clock driver gains SM8550 and SA8775P clocks, and the IPA clock
    is added on a variety of platforms
  - De-duplicate identical clks in Qualcomm SMD RPM clk driver
  - Add a few missing clocks across msm8998, msm8992, msm8916, qcs404 to
    Qualcomm SDM RPM clk driver
  - Various Qualcomm clk drivers use devm_pm_runtime_enable() to simplify
