Subject: [PATCH v2] dt-bindings: convert cros-ec-keyb.txt to yaml
Date:   Fri, 24 Jan 2020 11:41:58 +0100
Message-Id: <20200124104158.5008-1-dafna.hirschfeld@collabora.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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

-	 * 102ND key is not used for US keyboards.
