title: SpacemiT K1 GPIO controller

maintainers:
  - Yixun Lan <dlan@gentoo.org>

description:
  The controller's registers are organized as sets of eight 32-bit
  registers with each set of port controlling 32 pins.  A single
  interrupt line is shared for all of the pins by the controller.

properties:
  $nodename:
    pattern: "^gpio@[0-9a-f]+$"

    description:
      The first two cells are the GPIO bank index and offset inside the bank,
      the third cell should specify GPIO flag.

  "#interrupt-cells":
    const: 3
    description:
      The first two cells are the GPIO bank index and offset inside the bank,
      the third cell should specify interrupt flag. The controller does not
      support level interrupts, so flags of IRQ_TYPE_LEVEL_HIGH,
      IRQ_TYPE_LEVEL_LOW should not be used.
      Refer <dt-bindings/interrupt-controller/irq.h> for valid flags.
