[RFC v2 0/5] Input: goodix - platform/x86: touchscreen_dmi - Move quirks to touchscreen_dmi.c

[Hans de Goede]

Hi Dmitry, Bastien,

Here v2 of the patch series to move the DMI quirks for upside-down and
x-axis-inverted touchscreens in goodix.c to the generic x86 touchscreen
mechanism found in drivers/platform/x86/touchscreen_dmi.c .

As I mentioned in my reply to the v1 RFC I've dropped the:
"platform/x86: touchscreen_dmi: Match on ACPI HID instead of ACPI companion-dev-name"
patch from this version; and for completeness sake I've added a
couple of other pending touchscreen_dmi.c patches.

Note this is still marked as RFC for now since I have been unable to confirm
the ACPI HID for the touchscreen on the Cube I15-TC which is necessary
for the touchscreen_dmi.c code. I've send an email to the reporter and
the author of the patch adding the quirk for the Cube I15-TC.

As discussed in the "[PATCH] platform/x86: touchscreen_dmi: Add swap-x-y
quirk for Goodix touchscreen on Estar Beauty HD tablet" thread, I'll
prepare an immutable branch for Dmitry to pull once this is ready
for merging.

Note if I get no reply to the questions surrounding patch 2/5,
I'll probably just drop that patch and merge the rest.

Regards,

Hans

[RFC v2 1/5] Input: goodix - platform/x86: touchscreen_dmi - Move upside down quirks to touchscreen_dmi.c

[Hans de Goede]

Move the DMI quirks for upside-down mounted Goodix touchscreens from
drivers/input/touchscreen/goodix.c to
drivers/platform/x86/touchscreen_dmi.c,
where all the other x86 touchscreen quirks live.

Note the touchscreen_dmi.c code attaches standard touchscreen
device-properties to an i2c-client device based on a combination of a
DMI match + a device-name match. I've verified that the: Teclast X98 Pro,
WinBook TW100 and WinBook TW700 uses an ACPI devicename of "GDIX1001:00"
based on acpidumps and/or dmesg output available on the web.

This patch was tested on a Teclast X89 tablet.

[RFC v2 3/5] platform/x86: touchscreen_dmi: Add an extra entry for the upside down Goodix touchscreen on Teclast X89 tablets

[Hans de Goede]

Teclast X89 tablets come in 2 versions, with Windows pre-installed and with
Android pre-installed. These 2 versions have different DMI strings.

Add a match for the DMI strings used by the Android version BIOS.

Note the Android version BIOS has a bug in the DSDT where no IRQ is
provided, so for the touchscreen to work a DSDT override fixing this
is necessary as well.

[RFC v2 4/5] platform/x86: touchscreen_dmi: Add info for the Goodix GT912 panel of TM800A550L tablets

[Hans de Goede]

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/

I'm going to prepare an immutable branch for patches 1-4 of this series
(with patch 2 dropped since I haven't gotten any testing feedback for it).

Since this is an unrelated touchscreen quirk and I want to send it out in the
next pdx86-fixes pullreq for 5.13, I've added this to the pdx86 review-hans
and fixes branches now.

Regards,

Hans
