Workaround for using devices powered with 5V on the HY2.0-4P port

The 5V power on the HY2.0-4P is fed by the axp192. Therefore these devices must be initialized some time after the axp192 has started.

i2c:
  - id: bus_grove
    sda: GPIO32
    scl: GPIO33
    scan: True
    frequency: 100kHz
    ## Start after the axp192 has powered up
    ## In case an additional delay is needed this component may be helpful:

    setup_priority: 500

sensor:
  ## Example: anything connected to "i2c_id: bus_grove" should have a lower setup priority than bus_grove.
