    Subject[PATCH v3 3/4] ARM: dts: sun8i-a83t-tbs-a711: Add support for the vibrator motor
    Date
    The board has a vibrator mottor. Hook it to the input subsystem.

    According to the PMIC specification, LDO needs to be enabled (value 0b11)
    to achieve the specified max driving current of 150mA. We can't drive
    the motor with just GPIO mode.

    In GPIO mode the chip is probably just using the regular CMOS logic
    output circuitry (typically limited to around 20-35mA, but not specified
    in this datasheet).
