This patchset including modifying suspend/resume behavior add support to MT6358 PMIC.
MT6358 is the primary PMIC for MT8183 platform.
changes since v5:
- rewrite suspend/resume behavior for mfd driver.
- remove unused error handle for mfd driver.
- refine for better code quality in mfd driver.
- add MT6358 PMIC support to MT8183 evb.
- add signed-off-by for rtc patches.
