atmel,sam0-pinctrl¶

Vendor: Atmel Corporation

Description¶

Atmel SAM0 Pinctrl container node

The Atmel SAM0 pins implements following pin configuration option:

  * bias-pull-up
  * bias-pull-down
  * drive-strength
  * input-enable
  * output-enable
  * pinmux-enable

These options define devicetree flags that are converted to SoC flags at
ATMEL_SAM0_PIN_FLAGS().

Properties¶

Top level properties¶

These property descriptions apply to “atmel,sam0-pinctrl” nodes themselves. This page also describes child node properties in the following sections.

Properties not inherited from the base binding file.

(None)

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “atmel,sam0-pinctrl” compatible.

Name	Type	Details
`#address-cells`	`int`	number of address cells in reg property This property is required. Constant value: `1`
`#size-cells`	`int`	number of size cells in reg property This property is required. Constant value: `1`
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.

Child node properties¶

Name	Type	Details
`atmel,pins`	`phandle-array`
`pinmux-enable`	`boolean`	Assign pin to an embedded device peripheral
`bias-pull-up`	`boolean`	enable pull-up resistor
`bias-pull-down`	`boolean`	enable pull-down resistor
`drive-strength`	`int`	maximum sink or source current in mA
`input-enable`	`boolean`	enable input on pin (no effect on output, such as enabling an input buffer)
`output-enable`	`boolean`	enable output on a pin without actively driving it (such as enabling an output buffer)
