  4. Subject: [PATCH 036/102] soc: mediatek: PMIC wrap: SPI_WRITE needs a
    5. 

  5.  different bitmask for MT2701/7623
    6. 

  6. 

  7. Different SoCs will use different bitmask for the SPI_WRITE command. This
    8. 

  8. patch defines the bitmask in the pmic_wrapper_type struct. This allows us
    9. 

  9. to support new SoCs with a different bitmask to the one currently used.
