检测部分：对比两个宏：

CONFIG_ACCDET_EINT=y
# CONFIG_ACCDET_EINT_IRQ is not set

config ACCDET_EINT
    tristate "MediaTek ACCDET driver"
    ---help---

      ACCDET EINT support for MediaTek SOC

      If you want to use MediaTek ACCDET EINT from PMIC ACCDET itself,
      say Y or M here.

      If unsure, say N.

config ACCDET_EINT_IRQ
    tristate "MediaTek ACCDET driver"
    ---help---

      ACCDET EINT support for MediaTek SOC

      If you want to use MediaTek ACCDET EINT from AP GPIO,
