Merge tag 'soc-drivers-7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "There are lots of minor updates for driver subsystems managed through
  the soc tree (turris-omnia platform, cache driver, tee drivers,
  arm-cci, bus, memory) as well as soc vendor specific drivers
  (starfive, xilinx, microchip, nxp, amlogic, imx, renesas, samsung, ti,
  nvidia).

  The more notable changes are:

   - Larger updates for Qualcomm SoCs including support for SM8950
     (Maili) SM8975 (Hawi), Glymur, Shikra, and IPQ5424

   - Added SoC support for Exynos5515, Tegra264, Tegra410, R8A774A3, and
     MT8167 in existing drivers

   - Arm SCMI firmware driver support for ACPI PCC transport and module
     autoloading of protocol specific drivers

   - Apple crash log support for CrgA embedded controller"
