From 8d01cf643b3f8bc79c5b6bf18382b943143d9090 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 17 Apr 2021 19:31:05 +0200 Subject: [PATCH] platform/x86: touchscreen_dmi: Add info for the Teclast Tbook 11 tablet Add touchscreen info for the Teclast Tbook 11 tablet. This includes info for getting the firmware directly from the UEFI, so that the user does not need to manually install the firmware in /lib/firmware/silead. This change will make the touchscreen on these devices work OOTB, without requiring any manual setup.
