Merge tag 'soc-newsoc-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull new ARM SoC support from Arnd Bergmann:
 "There are two new SoC families this time, and both appear fairly
  similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are
  both dual-core Cortex-A35 based chips for the low-power industrial
  embedded market, and they mark the first 64-bit product in a widely
  used family of 32-bit Arm MCUs and SoCs.

  The way into the kernel is completely different here: The team at ST
  has a long history of working upstream with their STM32MP1 and other
  SoCs, and they produced a complete port to arm64 together with the
  initial announcement. Nuvoton also has multiple SoC product lines with
  current or previous upstream support, but those are maintained by
  third parties and are unrelated. The patch series from Nuvoton's Jacky
  Huang had to go through many revisisions to get to this point and is
  still missing a few drivers including the serial port for the moment.

  The branch contains the devicetree files as well as all the code
  changes, in order to have something that can be tested standalone"
