I think this might just work with the existing goodix driver, just
add the new GDIX1003 HID to the goodix_acpi_match table:

diff --git a/drivers/input/touchscreen/goodix.c b/drivers/input/touchscreen/goodix.c
index a3e8a51c9144..4b497540ed2d 100644
--- a/drivers/input/touchscreen/goodix.c
+++ b/drivers/input/touchscreen/goodix.c
@@ -1519,6 +1519,7 @@ MODULE_DEVICE_TABLE(i2c, goodix_ts_id);
 static const struct acpi_device_id goodix_acpi_match[] = {
 	{ "GDIX1001", 0 },
 	{ "GDIX1002", 0 },
+	{ "GDIX1003", 0 },
 	{ "GDX9110", 0 },
 	{ }
 };

Note I'm not sure this will work, but is worth a try.

Also please run:

sudo acpidump -o acpidump.txt

and send me a private (off-list) email with acpidump.txt
attached,

Regards,

Hans
