Add the Loongson series gpio binding with DT schema format using json-schema. Signed-off-by: Yinbo Zhu <zhuyinbo@xxxxxxxxxxx> --- Change in v2: 1. Drop "loongson,gpio_base" and "gpio-ranges" will cover it. 1. Drop "loongson,conf_offset", "loongson,out_offset", "loongson,in_offset", "loongson,support_irq" and kernel driver will initial them that depend compatible in kernel. 3. Fixup maintainer for this driver. .../bindings/gpio/loongson,ls-gpio.yaml | 126 ++++++++++++++++++ MAINTAINERS | 8 ++ 2 files changed, 134 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/loongson,ls-gpio.yaml diff --git a/Documentation/devicetree/bindings/gpio/loongson,ls-gpio.yaml b/Documentation/devicetree/bindings/gpio/loongson,ls-gpio.yaml new file mode 100644 index 000000000000..f54048d03d9b --- /dev/null +++ b/Documentation/devicetree/bindings/gpio/loongson,ls-gpio.yaml @@ -0,0 +1,126 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/gpio/loongson,ls-gpio.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Loongson series GPIO controller. + +maintainers: + - Yinbo Zhu <zhuyinbo@xxxxxxxxxxx> + +properties: + compatible: + enum: + - loongson,ls2k-gpio + - loongson,ls7a-gpio + + reg: + maxItems: 1 + + ngpios: + minimum: 1 + maximum: 64 + + "#gpio-cells": + const: 2 + + gpio-controller: true + + gpio-ranges: true + + interrupts: + minItems: 1 + maxItems: 64 + +required: + - compatible + - reg + - ngpios + - "#gpio-cells" + - gpio-controller + - gpio-ranges + - interrupts + +additionalProperties: false + +examples: + - | + #include <dt-bindings/interrupt-controller/irq.h> + + gpio0: gpio@1fe00500 { + compatible = "loongson,ls2k-gpio"; + reg = <0x1fe00500 0x38>; + ngpios = <64>; + #gpio-cells = <2>; + gpio-controller; + gpio-ranges = <&pctrl 0 0 15>, + <&pctrl 16 16 15>, + <&pctrl 32 32 10>, + <&pctrl 44 44 20>; + interrupt-parent = <&liointc1>; + interrupts = <28 IRQ_TYPE_LEVEL_LOW>, + <29 IRQ_TYPE_LEVEL_LOW>, + <30 IRQ_TYPE_LEVEL_LOW>, + <30 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <26 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <>, + <>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>, + <27 IRQ_TYPE_LEVEL_LOW>; + }; diff --git a/MAINTAINERS b/MAINTAINERS index 5114db9c8f32..7813b857c4a8 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -12051,6 +12051,14 @@ S: Maintained F: Documentation/devicetree/bindings/hwinfo/loongson,ls2k-chipid.yaml F: drivers/soc/loongson/loongson2_guts.c +LOONGSON SERIES GPIO DRIVER +M: Huacai Chen <chenhuacai@xxxxxxxxxx> +M: Yinbo Zhu <zhuyinbo@xxxxxxxxxxx> +L: linux-gpio@xxxxxxxxxxxxxxx +S: Maintained +F: Documentation/devicetree/bindings/gpio/loongson,ls-gpio.yaml +F: drivers/gpio/gpio-loongson.c + LSILOGIC MPT FUSION DRIVERS (FC/SAS/SPI) M: Sathya Prakash <sathya.prakash@xxxxxxxxxxxx> M: Sreekanth Reddy <sreekanth.reddy@xxxxxxxxxxxx> -- 2.31.1
