The Focaltech FTS driver supports several variants of focaltech touchscreens found in ~2018 era smartphones including variants found on the PocoPhone F1 and the SHIFT6mq which are already present in mainline. This driver is loosely based on the original driver from Focaltech and the patches submitted by Caleb Connolly previously[1] but has been simplified and largely reworked. Kindly let me know if any improvements are needed. Thanks.
