listenai,csk-pinctrl¶

Vendor: LISTENAI

Description¶

LISTENAI CSK600x Pin controller Node

Properties¶

Top level properties¶

These property descriptions apply to “listenai,csk-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 “listenai,csk-pinctrl” compatible.

Name	Type	Details
`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
`#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.

Child node properties¶

Name	Type	Details
`pinctrls`	`phandle-array`	Pin alternate function selection
`bias-disable`	`boolean`	disable any pin bias
`bias-high-impedance`	`boolean`	high impedance mode ("third-state", "floating")
`bias-bus-hold`	`boolean`	latch weakly
`bias-pull-up`	`boolean`	enable pull-up resistor
`bias-pull-down`	`boolean`	enable pull-down resistor
`bias-pull-pin-default`	`boolean`	use pin's default pull state
`drive-push-pull`	`boolean`	drive actively high and low
`drive-open-drain`	`boolean`	drive with open drain (hardware AND)
`drive-open-source`	`boolean`	drive with open source (hardware OR)
`drive-strength`	`int`	maximum sink or source current in mA
`drive-strength-microamp`	`int`	maximum sink or source current in μA
`input-enable`	`boolean`	enable input on pin (no effect on output, such as enabling an input buffer)
`input-disable`	`boolean`	disable input on pin (no effect on output, such as disabling an input buffer)
`input-schmitt-enable`	`boolean`	enable schmitt-trigger mode
`input-schmitt-disable`	`boolean`	disable schmitt-trigger mode
`input-debounce`	`int`	Takes the debounce time in μsec, as argument or 0 to disable debouncing
`power-source`	`int`	select between different power supplies
`low-power-enable`	`boolean`	enable low power mode
`low-power-disable`	`boolean`	disable low power mode
`output-disable`	`boolean`	disable output on a pin (such as disable an output buffer)
`output-enable`	`boolean`	enable output on a pin without actively driving it (such as enabling an output buffer)
`output-low`	`boolean`	set the pin to output mode with low level
`output-high`	`boolean`	set the pin to output mode with high level
`sleep-hardware-state`	`boolean`	indicate this is sleep related state which will be programmed into the registers for the sleep state
`slew-rate`	`int`	set the slew rate
`skew-delay`	`int`	This affects the expected clock skew on input pins and the delay before latching a value to an output pin. Typically indicates how many double-inverters are used to delay the signal.
