Hi AngeloGioacchino,

[obviously not a complete review, but wanted to call out regmap concern]

regmap is supposed to help with the paged registers, that is why I
recommended using it.

+	ret = regmap_noinc_read(ts->fw_regmap, NT36XXX_EVT_PROJECTID,
+				buf, sizeof(buf));

+
+	ts->fw_info.nvt_pid = (buf[1] << 8) + buf[0];

	ts->fw_info.nvt_pid = be16_to_cpu(pid);

Thanks.
