[ Upstream commit 3c785a06de ]
The usb-hid keyboard-dock for the Acer Switch 10 SW5-012 model declares
an application and hid-usage page of 0x0088 for the INPUT(4) report which
it sends. This reports contains 2 8-bit fields which are declared as
HID_MAIN_ITEM_VARIABLE.
The keyboard-touchpad combo never actually generates this report, except
when the touchpad is toggled on/off with the Fn + F7 hotkey combo. The
toggle on/off is handled inside the keyboard-dock, when the touchpad is
toggled off it simply stops sending events.
When the touchpad is toggled on/off an INPUT(4) report is generated with
the first content byte set to 120/121, before this commit the kernel
would report this as ABS_MISC 120/121 events.
Patch the descriptor to replace the HID_MAIN_ITEM_VARIABLE with
HID_MAIN_ITEM_RELATIVE (because no key-presss release events are send)
and add mappings for the 0x00880078 and 0x00880079 usages to generate
touchpad on/off key events when the touchpad is toggled on/off.

[ Upstream commit 5bf2f2f331 ]
The Acer One S1003 2-in-1 keyboard dock uses a Synaptics S910xx touchpad
which is connected to an ITE 8910 USB keyboard controller chip.
This keyboard has the same quirk for its rfkill / airplane mode hotkey as
other keyboards with ITE keyboard chips, it only sends a single release
event when pressed and released, it never sends a press event.
This commit adds this keyboards USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard. Note that like for the
Acer Aspire Switch 10 (SW5-012) the id-table entry matches on the
HID_GROUP_GENERIC generic group so that hid-ite only binds to the
keyboard interface and the mouse/touchpad interface is left untouched
so that hid-multitouch can bind to it.

commit beae56192a upstream.
Commit 8f18eca9eb ("HID: ite: Add USB id match for Acer SW5-012 keyboard
dock") added the USB id for the Acer SW5-012's keyboard dock to the
hid-ite driver to fix the rfkill driver not working.
Most keyboard docks with an ITE 8595 keyboard/touchpad controller have the
"Wireless Radio Control" bits which need the special hid-ite driver on the
second USB interface (the mouse interface) and their touchpad only supports
mouse emulation, so using generic hid-input handling for anything but
the "Wireless Radio Control" bits is fine. On these devices we simply bind
to all USB interfaces.
But unlike other ITE8595 using keyboard docks, the Acer Aspire Switch 10
(SW5-012)'s touchpad not only does mouse emulation it also supports
HID-multitouch and all the keys including the "Wireless Radio Control"
bits have been moved to the first USB interface (the keyboard intf).
So we need hid-ite to handle the first (keyboard) USB interface and have
it NOT bind to the second (mouse) USB interface so that that can be
handled by hid-multitouch.c and we get proper multi-touch support.
This commit changes the hid_device_id for the SW5-012 keyboard dock to
only match on hid devices from the HID_GROUP_GENERIC group, this way
hid-ite will not bind the the mouse/multi-touch interface which has
HID_GROUP_MULTITOUCH_WIN_8 as group.
This fixes the regression to mouse-emulation mode introduced by adding
the keyboard dock USB id.

The 258a:6a88 keyboard-dock shipped with the Prowise PT301 tablet is
likely another ITE based design. The controller die is directly bonded
to the PCB with a blob of black glue on top so there are no markings and
the 258a vendor-id used is unknown anywhere. But the keyboard has the
exact same hotkeys mapped to Fn+F1 - F10 as the other ITE8595 keyboard
I have *and* it has the same quirky behavior wrt the rfkill hotkey.
Either way as said this keyboard has the same quirk for its rfkill /
airplane mode hotkey as the ITE 8595 chip, it only sends a single release
event when pressed and released, it never sends a press event.
This commit adds the 258a:6a88 USB id to the hid-ite id-table, fixing

The ITE8595 keyboard uses the HID_GD_RFKILL_BTN usage code
from the Wireless Radio Controls Application Collection Microsoft
has defined for Windows 8 and later.
However it has a quirk, when the rfkill hotkey is pressed it does
generate a report for the collection, but the reported value is
always 0. Luckily it is the only button in this collection / report,
and it sends a report on release only, so receiving a report means the
button was pressed.
This commit adds a hid-ite driver which watches for the Wireless Radio
Controls Application Collection report and then reports a KEY_RFKILL event,
ignoring the value, making the rfkill on this keyboard work.
