Merge tag 'soc-drivers-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "The SoC driver changes once more consist of many small fixes and
  cleanups, that are to a large part the result of automated testing.

  On platform specific drivers, this includes SoC specific code for
  xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung,
  rockchip, renesas, ixp4xx. In firmware drivers, we see a similar
  picture for SCMI and qcomtee.

  Aside from these, we see actual new hardware support in a few areas:

   - The Apple platform gets a new driver for low power states

   - Updates to Qualcomm platform drivers add several new hardware
     specific features and additional SoCs.

   - Amlogic SoC support for A1 and T7 is added

   - The Mediatek MMSYS driver is refactored as a cleanup"
