  present on hardware with Apple SoCs such as the M1.

          I2C slave address field in PBMs input data

          patch for TPS25750.
          The patch address can be any value except 0x00, 0x20,
          0x21, 0x22, and 0x23

      Should contain the name of the default patch binary

      This is used when tps25750 doesn't have an EEPROM
      connected to it.
