Merge tag 'arm-soc-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC updates from Arnd Bergmann:
"The updates for arch/arm/mach-* platform code this time are mainly
minor cleanups.
Most notably, the DaVinci DM644x/DM646x SoC support gets removed. This
was also scheduled for later removal early next year, but Linus
Walleij asked for having them removed earlier to avoid problems for
the GPIO subsystem"
