Merge tag 'soc-drivers-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "Updates are across the usual driver subsystems with SoC specific
  drivers:

   - added soc specicific drivers for sophgo cv1800 and sg2044, qualcomm
     sm8750, and amlogic c3 and s4 chips.

   - cache controller updates for sifive chips, plus binding changes for
     other cache descriptions.

   - memory controller drivers for mediatek mt6893, stm32 and cleanups
     for a few more drivers

   - reset controller drivers for T-Head TH1502, Sophgo sg2044 and
     Renesas RZ/V2H(P)

   - SCMI firmware updates to better deal with buggy firmware, plus
     better support for Qualcomm X1E and NXP i.MX specific interfaces

   - a new platform driver for the crypto firmware on Cznic Turris
     Omnia/MOX

   - cleanups for the TEE firmware subsystem and amdtee driver

   - minor updates and fixes for freescale/nxp, qualcomm, google,
     aspeed, wondermedia, ti, nxp, renesas, hisilicon, mediatek,
     broadcom and samsung SoCs"
