Merge tag 'arm-fixes-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

ae971859 · Linus Torvalds <[email protected]> · 2024-01-26 13:09:38 -08:00

Pull arm SoC fixes from Arnd Bergmann:
 "There are a couple of devicetree fixes for samsung, riscv/sophgo, and
  for TPM device nodes on a couple of platforms.

  Both the Arm FF-A and the SCMI firmware drivers get a number of code
  fixes, addressing minor implementation bugs and compatibility with
  firmware implementations. Most of these bugs relate to the usage of
  xarray and rwlock structures and are fixed by Cristian Marussi"
