From a63945c3b56174537a4a655676fbe965f974b6b1 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Tue, 7 Mar 2023 10:17:15 -0600 Subject: [PATCH] ARM: dts: am57xx-idk: Add IDK displays and touchscreens This is a more interesting use of DT Overlays than the previous patches. Here we have two touchscreen modules. Each is compatible with, and can be attached to, either of the two AM57xx IDK development board variants (AM571x or AM572x). Due to the way the extension header was wired on the development boards, the touch sensor on the touchscreen modules will connect to different SoC pins when connected. For this the touch sensor is modeled as an additional overlay that is specific to the development board for which it is connected. Basically the LCD overlay can be swapped, but the touchscreen overlay that attaches to the LCD must be used with the corresponding base DT and not to the LCD.
