ChromeOS EC Keyboard
|
||||
|
||||
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.
|
||||
|
||||
This binding is based on matrix-keymap.txt and extends/modifies it as follows:
|
||||
|
||||
Required properties:
|
||||
- compatible: "google,cros-ec-keyb"
|
||||
|
||||
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.
|
||||
|
||||
|
||||
Example:
|
||||
|
||||
cros-ec-keyb {
|
||||
compatible = "google,cros-ec-keyb";
|
||||
keypad,num-rows = <8>;
|
||||
keypad,num-columns = <13>;
|
||||
google,needs-ghost-filter;
|
||||
/*
|
||||
* Keymap entries take the form of 0xRRCCKKKK where
|
||||
* RR=Row CC=Column KKKK=Key Code
|
||||
* The values below are for a US keyboard layout and
|
||||
* are taken from the Linux driver. Note that the
|
||||
* 102ND key is not used for US keyboards.
