Subject: [PATCH v6 0/8] soc: mediatek: MT8365 power support

Hi,

Thanks Angelo for the feedback, this version should fix all issues you
reported as well as the kernel test robot issues.

Thanks for any feedback!

Best,
Markus

Based on v6.4-rc1

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
