atmel,sam-mdio¶

Description¶

These nodes are “mdio” bus nodes.

Atmel SAM Family MDIO Driver node

Properties¶

Properties not inherited from the base binding file.

Name

Type

Details

pinctrl-0

phandles

PIO pin configuration for MDC, and MDIO signals.

For example the GMAC on SAME7x would be
  pinctrl-0 = <&pd8a_gmac_gmdc &pd9a_gmac_gmdio>;

protocol

string

MDIO bus framing protocol to use for communication. Most devices
support clause 22.

- clause 22: IEEE802.3 clause 22 frame format
- clause 45: IEEE802.3 clause 45 frame format
- micrel SMI: Micrel Serial Management Interface frame format

Default value: clause 22

Legal values: 'clause 22', 'clause 45', 'micrel SMI'

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,sam-mdio” compatible.

Name	Type	Details
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) This property is required. See Important properties for more information.
`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
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`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.
