1 ChromeOS EC Keyboard3 Google's ChromeOS EC Keyboard is a simple matrix keyboard implemented on4 a separate EC (Embedded Controller) device. It provides a message for reading5 key scans from the EC. These are then converted into keycodes for processing8 This binding is based on matrix-keymap.txt and extends/modifies it as follows:11 - compatible: "google,cros-ec-keyb"14 - google,needs-ghost-filter: True to enable a ghost filter for the matrix15 keyboard. This is recommended if the EC does not have its own logic or21 cros-ec-keyb {22 compatible = "google,cros-ec-keyb";[all …]
