From df5b5e555b356662a5e4a23c6774fdfce8547d54 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 2 Dec 2019 09:36:15 -0800 Subject: Input: goodix - add upside-down quirk for Teclast X89 tablet The touchscreen on the Teclast X89 is mounted upside down in relation to the display orientation (the touchscreen itself is mounted upright, but the display is mounted upside-down). Add a quirk for this so that we send coordinates which match the display orientation.
