[PATCH 0/2] Input: add support for the FocalTech FT3683G touchscreen

This series adds a binding and driver for the FocalTech FT3683G, a
capacitive touchscreen controller connected over SPI, found in the
Nothing Phone (3a).

The driver skeleton was written by hand, following existing in-tree
touchscreen drivers (goodix_berlin, himax_hx83112b, etc), with the SPI
transport ported from FocalTech's downstream driver. An LLM assistant
was then used for cleanup and best practices.
