CROS_EC Keyboard
ChromeOS EC Keyboard
The CROS_EC (Matrix Keyboard Protocol) allows communcation with a secondary
micro used for keyboard, and possible other features.
Google's ChromeOS EC Keyboard is a simple matrix keyboard implemented on
a separate EC (Embedded Controller) device. It provides a message for reading
key scans from the EC. These are then converted into keycodes for processing
by the kernel.
The CROS_EC keyboard uses this protocol to receive key scans and produce input
in U-Boot.
This binding is based on matrix-keymap.txt and extends/modifies it as follows:
Required properties :
- compatible : "google,cros-ec-keyb"
- google,key-rows : Number of key rows
- google,key-columns : Number of key columns
Required properties:
- compatible: "google,cros-ec-keyb"
Optional properties, in addition to those specified by the shared
matrix-keyboard bindings:
Optional properties:
- google,needs-ghost-filter: True to enable a ghost filter for the matrix
keyboard. This is recommended if the EC does not have its own logic or
hardware for this.
- linux,fn-keymap: a second keymap, same specification as the
matrix-keyboard-controller spec but to be used when the KEY_FN modifier
key is pressed.
- google,repeat-delay-ms : delay in milliseconds before repeat starts
- google,repeat-rate-ms : delay between each subsequent key press
- google,ghost-filter : enable ghost filtering for this device
Example, taken from daisy:
