microchip,xec-i2c-v2¶

Description¶

These nodes are “i2c” bus nodes.

Microchip I2C/SMB V2 controller

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`port_sel`	`int`	soc block mapping to pin This property is required.
`girqs`	`array`	array of GIRQ numbers [8:26] and bit positions [0:31] This property is required.
`pcrs`	`array`	PCR sleep register index and bit position This property is required.
`#girq-cells`	`int`	Constant value: `2`
`pcr-cells`	`int`	Constant value: `2`
`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 “microchip,xec-i2c-v2” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`#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`	`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
`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.

Specifier cell names¶

girq cells: girq_num, bitpos
pcr cells: regidx, bitpos
