platform/x86: touchscreen_dmi: Add quirk for y-inverted Goodix touchscreen on SUPI S10

2026-02-23T14:27:22+00:00

The touchscreen on the SUPI S10 tablet reports inverted Y coordinates, causing touch input to be mirrored vertically relative to the display. Add a quirk to set the "touchscreen-inverted-y" boolean device-property on the touchscreen device, so that the goodix_ts driver will fixup the coordinates.

Use 2-argument strscpy(), which is not only shorter but also provides an additional check that destination buffer is an array. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20240602090244.1666360-8-andy.shevchenko@gmail.com Reviewed-by: Hans de Goede Signed-off-by: Hans de Goede

platform/x86: touchscreen_dmi: Drop "silead,max-fingers" property

2024-06-03T09:10:46+00:00

The silead touchscreen driver now defaults to 10 fingers, so it is no longer necessary to have a "silead,max-fingers=10" property for each silead touchscreen model. Drop this property from all the configs. Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20240525193854.39130-3-hdegoede@redhat.com

platform/x86: touchscreen_dmi: Add support for setting touchscreen properties from cmdline

2024-05-27T09:42:57+00:00

On x86/ACPI platforms touchscreens mostly just work without needing any device/model specific configuration. But in some cases (mostly with Silead and Goodix touchscreens) it is still necessary to manually specify various touchscreen-properties on a per model basis. touchscreen_dmi is a special place for DMI quirks for this, but it can be challenging for users to figure out the right property values, especially for Silead touchscreens where non of these can be read back from the touchscreen-controller. ATM users can only test touchscreen properties by editing touchscreen_dmi.c and then building a completely new kernel which makes it unnecessary difficult for users to test and submit properties when necessary for their laptop / tablet model. Add support for specifying properties on the kernel commandline to allow users to easily figure out the right settings. See the added documentation in kernel-parameters.txt for the commandline syntax.
