Merge tag 'soc-fixes-5.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

3dc064d2 · Linus Torvalds <[email protected]> · 2021-08-06 11:41:12 -07:00

Pull ARM SoC fixes from Arnd Bergmann:
 "Lots of small fixes for Arm SoCs this time, nothing too worrying:

   - omap/beaglebone boot regression fix in gpt12 timer

   - revert for i.mx8 soc driver breaking as a platform_driver

   - kexec/kdump fixes for op-tee

   - various fixes for incorrect DT settings on imx, mvebu, omap, stm32,
     and tegra causing problems.

   - device tree fixes for static checks in nomadik, versatile, stm32

   - code fixes for issues found in build testing and with static
     checking on tegra, ixp4xx, imx, omap"
