Linus Torvalds b869e9f499 Another set of clk driver updates and fixes for the merge window. The
driver updates needed more time to bake in linux-next.
 
 Updates:
  - Support for more clk controllers in Qualcomm SoCs such as SM8350,
    SM8450, SDX75, SC8280XP, and IPQ9574
  - Runtime PM enablement of some more Qualcomm clk controllers
  - Various fixes to Qualcomm clk driver data to use correct clk_ops
    and to check halt bits properly
  - AT91 updates to modernize with clk_parent_data structures
 
 Fixes:
  - Remove "syscon" from dt binding fix for ti,j721e-system-controller
  - Fix determine rate in the Tegra driver that got wrecked by the
    refactorting of muxes this merge window

makes kernel configuration more difficult as many do not remember the

1. There won't be a single image for ARMv7 and ARMv8/9 SoCs.
2. Newer ARMv8/9 SoCs won't be running in arm32 emulation mode.

Luca Weiss e9a2db5caf clk: qcom: smd-rpm: conditionally enable scaling before doing handover
On older platforms like msm8226, msm8974 and msm8916 the driver in the
downstream kernel enables scaling first before doing the handover of the
clocks.

While this normally doesn't seem to cause noticeable problems, on
apq8026-asus-sparrow this causes the device to immediately reboot,
perhaps due to older rpm firmware that becomes unhappy.

On newer platforms the order has swapped and enabling scaling is done
after the handover, so let's introduce this behavior only conditionally
for msm8226 and msm8974 for now.
