Hans de Goede aaa40965d2 platform/x86: silead_dmi: Add silead, home-button property to some tablets
Add "silead,home-button" property to entries for tablets which have
a capacitive home button (typically a windows logo on the front).

This new property is checked for by the new capacitive home button
support in the silead touchscreen driver.

Hans de Goede 5c24c05efa platform/x86: silead_dmi: Fix GP-electronic T701 entry
The GP-electronic T701 has its LCD panel mounted upside-down, initially
my plan was to fix this by transparently rotating the image in the i915
driver (my "drm/i915: Deal with upside-down mounted LCD" patch), but
that approach has been rejected instead the kernel will now export
a "panel orientation" property on the drm-connector for the panel and
let userspace deal with it.

But userspace expects the touchscreen coordinates to match the panel
coordinates *before* applying any rotation, so now that we no longer hide
the upside-down-ness of the LCD panel from userspace the coordinates being
generated are wrong and we need to apply a rotation of 180 degrees to the
coordinates to fix this.

Dmitry Torokhov e105396398 platform/x86: silead_dmi - do not treat all devices as i2c_clients
I2C bus has both i2c clients and adapter devices, so we must be careful in
notifier code and verify that we are actually dealing with an i2c client
before using it as such.

Hans de Goede cef9dd85ac platform/x86: add support for devices with Silead touchscreens
On ACPI based tablets, the ACPI touchscreen node only contains info on
the gpio and the irq, and is missing any info on the axis. This info is
expected to be built into the tablet model specific version of the driver
shipped with the os-image for the device.

Add support for getting the missing info from a table built into the
driver, using dmi data to identify which entry of the table to use and
add info for the CUBE iwork8 Air and Jumper EZpad mini3 tablets on which
this code was tested / developed.
