Description

These nodes are “i2c” bus nodes.

Atmel SAM0 series SERCOM I2C node

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`clock-frequency`	`int`	Initial clock frequency in Hz

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-i2c” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`interrupts`	`array`	interrupts for device This property is required. See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information This property is required.
`clock-names`	`string-array`	name of each clock This property is required.
`dmas`	`phandle-array`	Optional TX & RX dma specifiers. Each specifier will have a phandle reference to the dmac controller, the channel number, and peripheral trigger source. For example dmas for TX, RX on SERCOM3 dmas = <&dmac 0 0xb>, <&dmac 0 0xa>;
`dma-names`	`string-array`	Required if the dmas property exists. This should be "tx" and "rx" to match the dmas property. For example dma-names = "tx", "rx";
`#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.
`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-names`	`string-array`	name of each register space
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM 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.
