[PATCH] dt-bindings: gpio: Create a trivial GPIO schema
Rob Herring (Arm)
robh at kernel.org
Tue Jul 1 15:53:50 PDT 2025
Many simple GPIO controllers without interrupt capability have the same
schema other than their compatible value. Combine all these bindings
into a single schema. The criteria to be included here is must use 2
cells, have no interrupt capability, have 0 or 1 "reg" entries, and
have no other resources (like clocks).
Note that "ngpios" is now allowed in some cases it wasn't before and
constraints on it have been dropped.
Signed-off-by: Rob Herring (Arm) <robh at kernel.org>

We could also do this for ones with interrupts, but that seems a bit
more varied.

-Required properties:
-- compatible : "snps,creg-gpio-hsdk" or "snps,creg-gpio-axs10x".
-- reg : Exactly one register range with length 0x4.
-- #gpio-cells : Since the generic GPIO binding is used, the
- amount of cells must be specified as 2. The first cell is the
- pin number, the second cell is used to specify optional parameters:
- See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
-- gpio-controller : Marks the device node as a GPIO controller.
-- ngpios: Number of GPIO pins.

-Example:
-
-gpio: gpio at f00014b0 {
- compatible = "snps,creg-gpio-hsdk";
- reg = <0xf00014b0 0x4>;
- gpio-controller;
- #gpio-cells = <2>;
- ngpios = <2>;
-};
