microchip,xec-kbd

Note

An implementation of a driver matching this compatible is available in drivers/input/input_xec_kbd.c.

Description

Microchip XEC keyboard matrix controller

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`girqs`	`array`	Array of pairs of GIRQ number and bit position This property is required.
`pcrs`	`array`	ADC PCR register index and bit position This property is required.
`row-size`	`int`	The number of rows in the keyboard matrix. This property is required.
`col-size`	`int`	The number of column in the keyboard matrix. This property is required.
`poll-period-ms`	`int`	Defines the poll period in msecs between between matrix scans, set to 0 to never exit poll mode. Defaults to 5ms if unspecified. Default value: `5`
`poll-timeout-ms`	`int`	How long to wait before going from polling back to idle state. Defaults to 100ms if unspecified. Default value: `100`
`debounce-down-ms`	`int`	Debouncing time for a key press event. Defaults to 10ms if unspecified. Default value: `10`
`debounce-up-ms`	`int`	Debouncing time for a key release event. Defaults to 20ms if unspecified. Default value: `20`
`settle-time-us`	`int`	Delay between setting column output and reading the row values. Defaults to 50us if unspecified. Default value: `50`
`actual-key-mask`	`array`	Keyboard scanning mask. For each keyboard column, specify which keyboard rows actually exist. Can be used to avoid triggering the ghost detection on non existing keys. No masking by default, any combination is valid.
`no-ghostkey-check`	`boolean`	Ignore the ghost key checking in the driver if the diodes are used in the matrix hardware.
`pinctrl-0`	`phandles`	Pin configuration/s for the first state. Content is specific to the selected pin controller driver implementation.
`pinctrl-1`	`phandles`	Pin configuration/s for the second state. See pinctrl-0.
`pinctrl-2`	`phandles`	Pin configuration/s for the third state. See pinctrl-0.
`pinctrl-3`	`phandles`	Pin configuration/s for the fourth state. See pinctrl-0.
`pinctrl-4`	`phandles`	Pin configuration/s for the fifth state. See pinctrl-0.
`pinctrl-names`	`string-array`	Names for the provided states. The number of names needs to match the number of states.

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-kbd” 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
`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.
`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
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`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
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`power-domains`	`phandle-array`	Power domain specifiers
`power-domain-names`	`string-array`	Provided names of power domain specifiers
`#power-domain-cells`	`int`	Number of cells in power-domains property
`zephyr,deferred-init`	`boolean`	Do not initialize device automatically on boot. Device should be manually initialized using device_init().
`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.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.
`zephyr,disabling-power-states`	`phandles`	List of power states that will disable this device power.
