Just const. Sure. But note that the example schema uses 'items' like this (e.g. for 'compatible' and 'clock-names'): https://docs.kernel.org/devicetree/bindings/writing-schema.html#annotated-example-schema Johan

The point is that clocks usually have just one list, so one "items:". For compatible there can be many and it leads to less readable code, e.g.: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/mmc/renesas,sdhi.yaml?h=v6.9-rc5#n15 Best regards, Krzysztof

Add a compatible string for the Elan eKTH5015M touch controller. Judging from the current binding and commit bd3cba00dcc6 ("HID: i2c-hid: elan: Add support for Elan eKTH6915 i2c-hid touchscreens"), eKTH5015M appears to be compatible with eKTH6915. Notably the power-on sequence is the same. While at it, drop a redundant label from the example.
