The driver under the hpe,gxp-gpio-pl will provide GPIO information from the CPLD interface. The CPLD interface represents all physical GPIOs. The GPIO interface with the CPLD allows use of interrupts. Signed-off-by: Nick Hawkins --- v5: *Removed use of gpio-gxp in favor of just supporting hpe,gxp-gpio-pl for now as the full gpio-gxp will require a much larger patchset *Modified commit description to reflect removal of hpe,gxp-gpio v4: *Fix min and max values for regs v3: *Remove extra example in examples *Actually fixed indentation on example - Aligned GPIO line names with " above. v2: *Put binding patch before the driver in the series *Improved patch description *Removed oneOf and items in compatible definition *Moved additionalProperties definition to correct spot in file *Fixed indentation on example *Improved description in .yaml --- .../bindings/gpio/hpe,gxp-gpio.yaml | 71 +++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/hpe,gxp-gpio.yaml diff --git a/Documentation/devicetree/bindings/gpio/hpe,gxp-gpio.yaml b/Documentation/devicetree/bindings/gpio/hpe,gxp-gpio.yaml new file mode 100644 index 000000000000..799643c1a0c2 --- /dev/null +++ b/Documentation/devicetree/bindings/gpio/hpe,gxp-gpio.yaml @@ -0,0 +1,71 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/gpio/hpe,gxp-gpio.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: HPE GXP gpio controllers + +maintainers: + - Nick Hawkins + +description: + Interruptable GPIO drivers for the HPE GXP that covers multiple interfaces + of both physical and virtual GPIO pins. + +properties: + compatible: + const: hpe,gxp-gpio-pl + + reg: + items: + - description: pl base gpio + - description: pl interrupt gpio + + reg-names: + items: + - const: base + - const: interrupt + + gpio-controller: true + + "#gpio-cells": + const: 2 + + gpio-line-names: + maxItems: 80 + + interrupts: + maxItems: 1 + +required: + - compatible + - reg + - reg-names + - gpio-controller + - "#gpio-cells" + +additionalProperties: false + +examples: + - | + gpio@51000300 { + compatible = "hpe,gxp-gpio-pl"; + reg = <0x51000300 0x7f>, <0x51000380 0x20>; + reg-names = "base", "interrupt"; + gpio-controller; + #gpio-cells = <2>; + interrupt-parent = <&vic0>; + interrupts = <24>; + gpio-line-names = + "IOP_LED1", "IOP_LED2", "IOP_LED3", "IOP_LED4", "IOP_LED5", "IOP_LED6", "IOP_LED7", "IOP_LED8", + "FAN1_INST", "FAN2_INST", "FAN3_INST", "FAN4_INST", "FAN5_INST", "FAN6_INST", "FAN7_INST", + "FAN8_INST", "FAN1_FAIL", "FAN2_FAIL", "FAN3_FAIL", "FAN4_FAIL", "FAN5_FAIL", "FAN6_FAIL", + "FAN7_FAIL", "FAN8_FAIL", "FAN1_ID", "FAN2_ID", "FAN3_ID", "FAN4_ID", "FAN5_ID", "FAN6_ID", + "FAN7_ID", "FAN8_ID", "IDENTIFY", "HEALTH_RED", "HEALTH_AMBER", "POWER_BUTTON", "UID_PRESS", + "SLP", "NMI_BUTTON", "RESET_BUTTON", "SIO_S5", "SO_ON_CONTROL", "PSU1_INST", "PSU2_INST", + "PSU3_INST", "PSU4_INST", "PSU5_INST", "PSU6_INST", "PSU7_INST", "PSU8_INST", "PSU1_AC", + "PSU2_AC", "PSU3_AC", "PSU4_AC", "PSU5_AC", "PSU6_AC", "PSU7_AC", "PSU8_AC", "PSU1_DC", + "PSU2_DC", "PSU3_DC", "PSU4_DC", "PSU5_DC", "PSU6_DC", "PSU7_DC", "PSU8_DC", "", "", "", "", + "", "", "", "", "", "", "", "", "", ""; + };
