This is compatible with the gpio-mmio. Add the compatible string to allow as below. Example: gpio0: gpio@91000000 { compatible = "opencores,gpio", "brcm,bcm6345-gpio"; reg = <0x91000000 0x1>, <0x91000001 0x1>; reg-names = "dat", "dirout"; gpio-controller; #gpio-cells = <2>; status = "okay"; }; Link: https://opencores.org/projects/gpio Signed-off-by: Stafford Horne Acked-by: Conor Dooley Link: https://lore.kernel.org/r/20251217080843.70621-2-shorne@gmail.com Signed-off-by: Bartosz Golaszewski --- diff --git a/Documentation/devicetree/bindings/gpio/gpio-mmio.yaml b/Documentation/devicetree/bindings/gpio/gpio-mmio.yaml index b4d55bf6a2854..6fcf5fd2cb66f 100644 --- a/Documentation/devicetree/bindings/gpio/gpio-mmio.yaml +++ b/Documentation/devicetree/bindings/gpio/gpio-mmio.yaml @@ -18,11 +18,16 @@ description: properties: compatible: - enum: - - brcm,bcm6345-gpio - - ni,169445-nand-gpio - - wd,mbl-gpio # Western Digital MyBook Live memory-mapped GPIO controller - - intel,ixp4xx-expansion-bus-mmio-gpio + oneOf: + - enum: + - brcm,bcm6345-gpio + - ni,169445-nand-gpio + - wd,mbl-gpio # Western Digital MyBook Live memory-mapped GPIO controller + - intel,ixp4xx-expansion-bus-mmio-gpio + - items: + - enum: + - opencores,gpio + - const: brcm,bcm6345-gpio big-endian: true
