[RFC 0/4] Input: goodix - platform/x86: touchscreen_dmi - Move quirks to touchscreen_dmi.c

[Hans de Goede]

Hi Dmitry, Bastien,

As discussed before here is a patch series which moves 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 .

Note this is 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.

Since this patch touches files in both the Input and pdx86 subsystems
we need to discuss how to merge this. Dmitry I can create an immutable
branch which these 4 patches on top of 5.13-rc1 (once released) and
then send you a pull-req for that im-branch, would that work for you ?

Regards,

Hans

[RFC 1/4] platform/x86: touchscreen_dmi: Match on ACPI HID instead of ACPI companion-dev-name

[Hans de Goede]

The ACPI-companion device's dev_name() (which gets used as
i2c_client->name for I2C-devices) consists of the ACPI HID to a ":##"
suffix, which typically is ":00" but if there is more then one ACPI
fwnode with the same HID it may be ":01" etc.

On some tablets there are multiple ACPI fwnode-s describing the
touchscreen, one for each I2C bus the device may be connected to.
In this case we get ACPI-companion devices with e.g. "GDIX1001:00"
and "GDIX1001:01" as dev_name(). This makes matching on the dev_name()
as we have been doing inconvinient if we want to share a ts_dmi_data
struct between device's which need the same set of device-properties,
bit have their touchscreen on different busses leading to different
":##" suffixes.

Since there always is only one touchscreen, there is no reason to
include the suffix in the matching.

Change the code to match on ACPI HID instead of ACPI-companion device's
dev_name() so that it is more flexible.

Re: [RFC 1/4] platform/x86: touchscreen_dmi: Match on ACPI HID instead of ACPI companion-dev-name

Self NACK I thought this was a good idea, but I forgot that every
kernel devel-cycle a few new quirks get added to touchscreen_dmi.c
and that those are typically backported to the stable series.

This patch would make all this a big hassle for a tiny gain, so lets
I'm dropping it.

[RFC 2/4] 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 4/4] 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.
