Previously, Message Processor always generated
CRC byte at end of message.
Now(version 8), this CRC byte is generated only upon request.
To request that a checksum is generated, the MSBit
of the address of the Message Processor object is set to 1.
By default the CRC byte is not generated, reading the CRC byte
will remove new messages from IC causing lost touches.
Added control flag and message size correction for this feature.

Send both fingers using the new multitouch protocol in addition to
the old single finger event and second finger ABS_HAT* hack.
The new protocol does not specify how to report up events. To make
sure the user-space frameworks can generate up events, we send at
least one event where ABS_MT_TOUCH_MAJOR is zero before we stop
sending events for a finger.

ADS7845 is a controller for 5-wire touch screens and somewhat
different from 7846. It requires three serial communications to
accomplish one complete conversion. Unlike 7846 it doesn't allow
Z1-/Z2- position measurement.
The patch extends the ads7846 driver to also support ads7845.
The packet struct is extended to contain needed command and
conversion buffers. ads7846_rx() and ads7846_rx_val() now
differentiate between 7845 and 7846 case. ads7846_probe() is
modified to setup ads7845 specific command and conversion
messages and to switch ads7845 into power-down mode, since
this is needed to be prepared to respond to pendown interrupts.
