Subject: [PATCH v5 0/2] Input: cros-ec-keyb: Better matrixless support

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@chromium.org):
 * 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@chromium.org):
 * 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@chromium.org):
 * 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@chromium.org):
 * Better enforcement of properties in DT binding
 * Skip registration by means of adding compatible to device id list
