While this touchscreen's communications are based on the generic "i2c-over-hid" protocol, it needs special power sequencing and thus gets its own compatible and bindings. Signed-off-by: Douglas Anderson --- Changes in v3: - Removed Benjamin as a maintainer. - Fixed compatible in example. - Updated description.
