Commit Message

Yoshihiro Shimoda June 26, 2020, 9:32 a.m. UTC 
Add regulator-off-in-suspend property into eMMC related regulator-fixed
nodes because PSCI on the boards will turn the regulators off in suspend.

By this property, the regulator's status will be disabled in suspend.
MMC subsystem can get the condition and then eMMC condition will
be better than before.
 before:
  - enter sleep mode and then turn the vmmc and vqmmc off.
 after:
  - call mmc_poweroff_nofity() and then turn the vmmc and vqmmc off.
