Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC platform updates from Olof Johansson:
"SoC changes, a substantial part of this is cleanup of some of the
older platforms that used to have a bunch of board files.
In particular:
- Remove non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP
platforms, moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP"
