-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
