Input: add MStar MSG2638 touchscreen driver Add support for the msg2638 touchscreen IC from MStar. Firmware handling, wakeup gestures and other specialties are not supported. This driver reuses zinitix.c structure, while the checksum and irq handler functions are based on out-of-tree driver for Alcatel Idol 3 (4.7").
