On some x86 tablets with a silead touchscreen the windows logo on the

Do we know which ones?
Not really, but since we need to pass resolution info, etc. through
device-properties (set in drivers/platform/x86/silead_dmi.c) we
could add a device-property for this, this should also work for
devicetree based models (although I've only seen the capacitive
home button as the Windows logo on X86 hardware so far).
Can we only set it in capabilities for devices
that actually have it?
If we add a device property for it, yes. I guess that is how
you want me to handle this, so you will want a v2 which
keys the enabling of the home button from a device-prop ?
