Merge tag 'arm-drivers-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM driver updates from Arnd Bergmann:
 "There are minor updates to SoC specific drivers for chips by Rockchip,
  Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom.

  Noteworthy driver changes include:

   - Several conversions of DT bindings to yaml format.

   - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.

   - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
     and support for more chips in the RPMh power domains and the
     soc-id.

   - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.

   - Apple M1 gains support for the on-chip NVMe controller, making it
     possible to finally use the internal disks. This also includes SoC
     drivers for their RTKit IPC and for the SART DMA address filter.

  For other subsystems that merge their drivers through the SoC tree, we
  have

   - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
     SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
     now has a cache for firmware argument structures as an
     optimization, and SCMI now supports the 3.1 version of the
     specification.

   - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI
     drivers

   - Memory controller updates for Tegra, and a few updates for other
     platforms"
