Input: imagis - use FIELD_GET where applicable

2024-04-13T11:05:13+00:00

[ Upstream commit c0ca3dbd03d66c6b9e044f48720e6ab5cef37ae5 ] Instead of manually extracting certain bits from registers with binary ANDs and shifts, the FIELD_GET macro can be used. With this in mind, the *_SHIFT macros can be dropped.

Input: add Imagis touchscreen driver

2022-03-21T05:00:12+00:00

Add support for the IST3038C touchscreen IC from Imagis, based on downstream driver. The driver supports multi-touch (10 touch points) The IST3038C IC supports touch keys, but the support isn't added because the touch screen used for testing doesn't utilize touch keys. Looking at the downstream driver, it is possible to add support for other Imagis ICs of IST30**C series.
