ec42d4481e Input: usbtouchscreen - ignore eGalax screens supporting HID protocol
The newer versions of the eGalax/EETI screen implement the HID protocol.
The device IDs are still the same, but the USB interface descriptor shows
the device being of HID class. Change usbtouchscreen to ignore the HID
models as they are handled properly by usbhid.

62aa366d9b Input: usbtouchscreen - fix buffer overflow, make more egalax work
Fix a buffer overflow in mutli-packet handling code.  The overflow can
only happen with eGalax devices and is even there very unlikely (only
non-report packet are affected any only when truncated after the first
byte).

Also changes the mutli-packet handling code not to drop unknown packets,
but rather just drop one byte.  This allows synchronizing on report packets
in the data stream.  It's required for some egalax devices to work at all.

Also remove the pointless 'flags' member of the device struct and set the
version number to 0.6, plus some minor cleanups.

7b19ada2ed get rid of input BIT* duplicate defines
get rid of input BIT* duplicate defines

use newly global defined macros for input layer. Also remove includes of
input.h from non-input sources only for BIT macro definiton. Define the
macro temporarily in local manner, all those local definitons will be
removed further in this patchset (to not break bisecting).
BIT macro will be globally defined (1<<x)

2a8281d72d Input: usbtouchscreen - support DMC devices with empty EEPROM
A reply of 0x0600 means all OK, 0x1501 means OK, but EEPROM empty.
The behavior with an empty EEPROM is the same as without one at all
so do not fail loading the driver.

7b6dff982b Input: usbtouchscreen - correctly set 'phys'
This patch fixes a nasty typo in usbtouchscreen driver. The typo
is inherited from the original mtouchusb. It used to make the input
subsytem to incorrectly report the physical device ids to userspace
that in turn is very confusing for, e.g. XInput hotplug facilities
in setups with multiple identical touchscreens.

df561fcd44 Input: usbtouchscreen - add support for IRTOUCHSYSTEMS touchscreens
This patch adds support for IRTOUCHSYSTEMS (or UNITOP) infrared touchscreens.

The touchscreen sends data in 8-byte packets.
BYTE 0 - unknown meaning, seen only one value: 0x54
BYTE 1 - unknown meaning, 3 lowest bits indicate touch state
        values seen: 0x81, 0x82 or 0x83
        bit 0 = set if the screen is touched and was not touched before (touch
        bit 1 = set if the screen is touched and was touched (dragging)
        bit 2 = set if the touch was ended (release)
BYTES 2 and 3 - X position, high-order-byte first, range = 0 to 0x0FFF
BYTES 4 and 5 - Y position, high-order-byte first, range = 0 to 0x0FFF
BYTE 6 - unknown meaning, seen only one value: 0xFF
BYTE 7 - unknown meaning, seen only one value: 0x00
