Instead of looking at the differences between the protocols, which don't look insurmountable (a switch statement in a few places, right?), you should look at the code you could share: - power management - ESD support - ACPI support - the support for variants in goodix.c (911-variants, and 967-variants) - ability to read and write config data to the device Taking this into account (and the fact that I can't read Chinese that well, so my reading of the specs is cursory), would it make sense to merge the 2 drivers? CC'ing Irina about this.
