Subject: [PATCH v8 0/8] soc: mediatek: MT8365 power support

Hi,

no real changes in this update. Rebase to v6.6-rc2 and according change
of directory.

Thanks for any feedback!

Best,
Markus

Based on v6.6-rc2

Changes in v8:
- Rebased to v6.6-rc2
- Moved changes from drivers/soc to drivers/pmdomain

Changes in v7:
- Rebased to v6.5-rc1
- Fixed a couple of small style issues pointed out by Angelo

Changes in v6:
- Change flags field to be u8 instead of u32
- Use macro concatenation to simplify BUS_PROT macros:
  BUS_PROT_WR(_hwip, ...) etc.
- Use the final bit values for scpsys_bus_prot_flags from the beginning
  of the series.
- Changed scpsys_domain_data->caps to be u16 to accommodate the new flag
  MTK_SCPD_STRICT_BUS_PROTECTION.

Changes in v5:
- Create defines for all registers and bits in mt8365 power domain patch
- Redesign scpsys_bus_prot_data to use flags to store reg_update,
  clr_ack as well as the difference between SMI and INFRACFG. The code
  uses the appropriate regmap depending on the flags.
- The WAY_EN patch now uses two flags, one for inverted operations
  'BUS_PROT_INVERTED' and one to use infracfg-nao for the status flags
  'BUS_PROT_STA_COMPONENT_INFRA_NAO'.

Changes in v4:
- Redesigned WAY_EN patch and split it up in smaller patches.
- Added two documentation patches.
- Added mediatek,infracfg-nao field to the binding.

Changes in v3:
- Mainly redesigned WAY_EN patch to be easier to understand
- Rebased onto v6.0-rc1
- Several other stuff that is described in the individual patches

Changes in v2:
- Updated error handling path for scpsys_power_on()
- Minor updates described in each patch
