Thanks to owner of the repository we found the solution adding this to the
drivers/platform/x86/silead_dmi.c:
First this section
but is optional if i understood right the important things is to have a DMI
match:
static const struct property_entry mediacom_w700_props[] = {
PROPERTY_ENTRY_U32("touchscreen-size-x", 884),
PROPERTY_ENTRY_U32("touchscreen-size-y", 632),
PROPERTY_ENTRY_STRING("firmware-name",
"gsl1686-surftab-wintron70-st70416-6.fw"),
PROPERTY_ENTRY_U32("silead,max-fingers", 10),
PROPERTY_ENTRY_BOOL("silead,home-button"),
{ }
};
The the DMI_MARTCH section:
{
/* Mediacom WinPad 7.0 W700 */
.driver_data = (void *)&surftab_wintron70_st70416_6_data,
.matches = {
DMI_MATCH(DMI_SYS_VENDOR, "MEDIACOM"),
DMI_MATCH(DMI_PRODUCT_NAME, "WinPad 7 W10 - WPW700"),
},
},

Bug description:
I' m using a tablet that is sold with Windows 10.
The firmware extracted from the special driver are already available here
https://github.com/onitake/gsl-firmware/tree/master/firmware/trekstor/surftab7old.
(I discovered that the Mediacom drivers are the same as those for TrekStor, a
company that also works with Mediacom.Mediacom Winpad 7.0 W700 corresponds at
SurfTab wintron 7.0 ST70416-6).
That repository states that i need to recompile the kernel.
I don' t know how here
https://unix.stackexchange.com/questions/466571/recompile-a-kernel-including-a-firmware?noredirect=1#comment850048_466571
there is my question about this problem.
It would be nice if the linux-kernel would support the tablet touchscreen by
default.
My kernel is 4.15.0-33-generic.
