    - 0x06: Bump customer use word
    - 0x28:
      - Port information: Drop try.Src - not needed and cofuses DR use
      - Type-C Current: Use weakest pullup - we only want to provide 500mA
        without a PD contract.
      - Over Voltage Protection Usage: Disconnect at trip point
      - Try.Src: Disable - wo have no interest in charging a laptop
      - Process Swap To Source: disable, we're a source initially
      - Process VCONN Swap: Disable, we're a VConn source initially
        and don't want to sink VConn
      - Initiate VCONN Swap: disable, we're a source initially if required.
      - Automatic Sink Capabilities Request: Disable, sink will make itself
        clear if necessary.
    - 0x33:
      - Limit number of sink PDOs to 1 (leaving 5V/3A)
      - Use 0.5/1/3A min/normal/max operating current
    - 0x37:
      - Autonegotiate Variable Sink Enable: disable, just support fixed
        sinks for now
      - Autonegotiate Battery Sink Enable: disable, just support fixed
        sinks for now
      - Offer priority: Choose highest current
      - Automatically Calculate Min Power Required: Disable
      - Minimum Power Required: 5W, that's enough as a start
