[ Upstream commit fcd8cf0e3e48f4c66af82c8e799c37cb0cccffe0 ] 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 Signed-off-by: Sasha Levin <sashal@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
