This is a followup to my previous patch[1] that skips keyboard registration when the matrix properties aren't present. This adds a compatible string for this scenario so we can ease existing DTBs over to the new design. Changes from v4 (https://lore.kernel.org/r/20220503204212.3907925-1-swboyd@xxxxxxxxxxxx): * Make switches compatible fail probe if no switches present * Add description to compatible list Changes from v3 (https://lore.kernel.org/r/20220503042242.3597561-1-swboyd@xxxxxxxxxxxx): * s/register_keyboard/has_keyboard/ * Pick up review tags * Indicate properties are required in example #2 in yaml file Changes from v2 (https://lore.kernel.org/r/20220429233112.2851665-1-swboyd@xxxxxxxxxxxx): * Drop rows/cols check now that compatible schema handles it * Make binding require rows,cols,keymap for cros-ec-keyb compatible Changes from v1 (https://lore.kernel.org/r/20220427203026.828183-1-swboyd@xxxxxxxxxxxx): * Better enforcement of properties in DT binding * Skip registration by means of adding compatible to device id list Stephen Boyd (2): dt-bindings: google,cros-ec-keyb: Introduce switches only compatible Input: cros-ec-keyb - skip keyboard registration w/o cros-ec-keyb compatible .../bindings/input/google,cros-ec-keyb.yaml | 91 +++++++++++++++++-- drivers/input/keyboard/cros_ec_keyb.c | 26 ++++-- 2 files changed, 101 insertions(+), 16 deletions(-) Cc: Krzysztof Kozlowski <krzk+dt@xxxxxxxxxx> Cc: Rob Herring <robh+dt@xxxxxxxxxx> Cc: <devicetree@xxxxxxxxxxxxxxx> Cc: Benson Leung <bleung@xxxxxxxxxxxx> Cc: Guenter Roeck <groeck@xxxxxxxxxxxx> Cc: Douglas Anderson <dianders@xxxxxxxxxxxx> Cc: Hsin-Yi Wang <hsinyi@xxxxxxxxxxxx> Cc: "Joseph S.
