  4. Subject: [PATCH 037/102] soc: mediatek: PMIC wrap: move wdt_src into the
    5. 

  5.  pmic_wrapper_type struct
    6. 

  6. 

  7. Different SoCs will use different bitmask for the wdt_src. This patch
    8. 

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

  9. support new SoCs with a different bitmask to the one currently used.
    10.
