Subject: [PATCH] dt-bindings: convert cros-ec-keyb.txt to yaml
Convert the binding file cros-ec-keyb.txt to yaml format.
This was tested and verified on ARM and ARM64 with:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/input/cros-ec-keyb.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/input/cros-ec-keyb.yaml

-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
