    mfd: axp20x: Add support for AXP813 PMIC · 7303733a
    Chen-Yu Tsai authored
    The X-Powers AXP813 PMIC is normally used with Allwinner's A83T SoC.
    It has the same range of functions as other X-Powers PMICs, such as
    DC-DC buck converter and linear regulator outputs, AC-IN and VBUS
    power supplies, power button trigger, GPIOs, ADCs, and a battery
    charger.
    
    Note that the IRQ table given in the datasheet is incorrect: in IRQ
    enable/status registers 1, there are separate IRQs for ACIN and VBUS,
    instead of bits [7:5] being the same as bits [4:2]. So it shares the
    same IRQs as the AXP803, rather than the AXP288.
    
    This patch adds basic mfd support for it, with only the power button
    enabled.
