    Subject[PATCH v3 10/21] arm64: dts: hi3660: add power key dts node
    Date
    From: Chen Jun <chenjun14@huawei.com>

    We use gpio_034 as power key on hikey960, and set gpio with pull-up
    state, when key press the voltage on the gpio will come to lower, and
    power key event will be reported.
