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 Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20210504185746.175461-5-hdegoede@redhat.com Signed-off-by: Sasha Levin --- drivers/platform/x86/touchscreen_dmi.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) diff --git a/drivers/platform/x86/touchscreen_dmi.c b/drivers/platform/x86/touchscreen_dmi.c index 8b9926a9db7e..424cf2a84744 100644 --- a/drivers/platform/x86/touchscreen_dmi.c +++ b/drivers/platform/x86/touchscreen_dmi.c @@ -316,6 +316,18 @@ static const struct ts_dmi_data gdix1001_01_upside_down_data = { .properties = gdix1001_upside_down_props, }; +static const struct property_entry glavey_tm800a550l_props[] = { + PROPERTY_ENTRY_STRING("firmware-name", "gt912-glavey-tm800a550l.fw"), + PROPERTY_ENTRY_STRING("goodix,config-name", "gt912-glavey-tm800a550l.cfg"), + PROPERTY_ENTRY_U32("goodix,main-clk", 54), + { } +}; + +static const struct ts_dmi_data glavey_tm800a550l_data = { + .acpi_name = "GDIX1001:00", + .properties = glavey_tm800a550l_props, +}; + static const struct property_entry gp_electronic_t701_props[] = { PROPERTY_ENTRY_U32("touchscreen-size-x", 960), PROPERTY_ENTRY_U32("touchscreen-size-y", 640), @@ -1055,6 +1067,15 @@ const struct dmi_system_id touchscreen_dmi_table[] = { DMI_MATCH(DMI_PRODUCT_NAME, "eSTAR BEAUTY HD Intel Quad core"), }, }, + { /* Glavey TM800A550L */ + .driver_data = (void *)&glavey_tm800a550l_data, + .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "AMI Corporation"), + DMI_MATCH(DMI_BOARD_NAME, "Aptio CRB"), + /* Above strings are too generic, also match on BIOS version */ + DMI_MATCH(DMI_BIOS_VERSION, "ZY-8-BI-PX4S70VTR400-X423B-005-D"), + }, + }, { /* GP-electronic T701 */ .driver_data = (void *)&gp_electronic_t701_data,
