Pins configuration for Samsung S3C/S5P/Exynos SoC pin controller. The values used for config properties should be derived from the hardware manual and these values are programmed as-is into the pin pull up/down and driver strength register of the pin-controller. See also Documentation/devicetree/bindings/pinctrl/samsung,pinctrl.yaml for additional information and example. properties: samsung,pins: description: | List of pins to configure. For initial and sleep states, the maximum number is one pin. In other cases there is no upper limit. The pins should use lowercase names matching hardware manual, e.g. for GPA0 bank: gpa0-0, gpa0-1, gpa0-2. $ref: /schemas/types.yaml#/definitions/string-array samsung,pin-function: description: | The pin function selection that should be applied on the pins listed in the child node is specified using the "samsung,pin-function" property. The value of this property that should be applied to each of the pins listed in the "samsung,pins" property should be picked from the hardware manual of the SoC for the specified pin group. This property is optional in the child node if no specific function selection is desired for the pins listed in the child node. The value of this property is used as-is to program the pin-controller function selector register of the pin-bank. $ref: /schemas/types.yaml#/definitions/uint32 minimum: 0 maximum: 15 samsung,pin-drv: description: Drive strength configuration. $ref: /schemas/types.yaml#/definitions/uint32 minimum: 0 maximum: 15 samsung,pin-pud: description: Pull up/down configuration. $ref: /schemas/types.yaml#/definitions/uint32 enum: [0, 1, 2, 3] samsung,pin-val: description: Initial value of pin output buffer. $ref: /schemas/types.yaml#/definitions/uint32 enum: [0, 1] samsung,pin-con-pdn: description: Function in power down mode. $ref: /schemas/types.yaml#/definitions/uint32 enum: [0, 1, 2, 3] samsung,pin-pud-pdn: description: Pull up/down configuration in power down mode. $ref: /schemas/types.yaml#/definitions/uint32 enum: [0, 1, 2, 3] required: - samsung,pins additionalProperties: false
