There are two crucial drivers to make Intel MID platforms functional in U-Boot: SCU which stands for System Controller Unit PMU which stands for Power Management Unit
Since v2: - resend with cover letter including changes from previous versions
Since v1:
Common: - convert to use REGMAP instead of constant addressed IO - rewrite as UCLASS_SYSCON modules - move to arch/x86/lib since it's related to x86 only and there are already another UCLASS_SYSCON modules there
SCU: - convert function documentation to have header and body and be consistent - shrink header and remove unneeded attributes - drop busy loop counter from 3m to 100k as per driver in Linux kernel
PMU: - convert to be more generic and move Tangier related part to its own folder (the latter out of scope of this series)
