Subject: [PATCH] dt-bindings: gpio: Convert microchip,pic32mzda-gpio to DT schema
Date: Mon, 14 Jul 2025 15:28:06 -0500 [thread overview]
Message-ID: <20250714202807.3010652-1-robh@kernel.org> (raw)
Convert the Microchip PIC32 GPIO binding to DT schema format. It's a
straight forward conversion.

-* Microchip PIC32 GPIO devices (PIO).
-
-Required properties:
- - compatible: "microchip,pic32mzda-gpio"
- - reg: Base address and length for the device.
- - interrupts: The port interrupt shared by all pins.
- - gpio-controller: Marks the port as GPIO controller.
- - #gpio-cells: Two. The first cell is the pin number and
- the second cell is used to specify the gpio polarity as defined in
- defined in <dt-bindings/gpio/gpio.h>:
- 0 = GPIO_ACTIVE_HIGH
- 1 = GPIO_ACTIVE_LOW
- 2 = GPIO_OPEN_DRAIN
- - interrupt-controller: Marks the device node as an interrupt controller.
- - #interrupt-cells: Two. The first cell is the GPIO number and second cell
- is used to specify the trigger type as defined in
- <dt-bindings/interrupt-controller/irq.h>:
- IRQ_TYPE_EDGE_RISING
- IRQ_TYPE_EDGE_FALLING
- IRQ_TYPE_EDGE_BOTH
- - clocks: Clock specifier (see clock bindings for details).
- - microchip,gpio-bank: Specifies which bank a controller owns.
- - gpio-ranges: Interaction with the PINCTRL subsystem.
-
-Example:
-
-/* PORTA */
-gpio0: gpio0@1f860000 {
