The Bay Trail Glavey TM800A550L tablet, which ships with Android installed from the factory, uses a GT912 touchscreen controller which needs to have its firmware uploaded by the OS to work (this is a first for a x86 based device with a Goodix touchscreen controller). Add a touchscreen_dmi entry for this which specifies the filenames to use for the firmware and config files needed for this. Note this matches on a GDIX1001 ACPI HID, while the original DSDT uses a HID of GODX0911. For the touchscreen to work on these devices a DSDT override is necessary to fix a missing IRQ and broken GPIO settings in the ACPI-resources for the touchscreen. This override also changes the HID to the standard GDIX1001 id typically used for Goodix touchscreens. The DSDT override is available here: https://fedorapeople.org/~jwrdegoede/glavey-tm800a550l-dsdt-override/ Reviewed-by: Bastien Nocera <hadess@hadess.net> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20210504185746.175461-5-hdegoede@redhat.com |
