Given that this is already stated by the compatible, would it be
reasonable to make this use the marketing name instead?

(I.e. "Sony Mobile Xperia XA2 Ultra")

> +	compatible = "sony,discovery-row", "qcom,sdm630", "qcom,sdm630-mtp";

Does the -mtp one have any significance? Otherwise I would like you to
drop this - given that this isn't going to be compatible with the actual
MTP hardware.

/soc is for mmio devices, as such gpio_keys should be moved outside
"soc".
