   4 Subject: [PATCH 036/102] soc: mediatek: PMIC wrap: SPI_WRITE needs a
   5  different bitmask for MT2701/7623
   6
   7 Different SoCs will use different bitmask for the SPI_WRITE command. This
   8 patch defines the bitmask in the pmic_wrapper_type struct. This allows us
   9 to support new SoCs with a different bitmask to the one currently used.
