[v1,0/2] Input: psmouse: Introduce PixArt driver

Message

Hi all:

This patchset try to introduce the PixArt touchpad driver.

Unfortunately, due to the current design of the PixArt touchpad hardware
and FW, our single packet data width needs 11 bytes/15 bytes to receive
three-finger/four-finger data in absolute coordinate mode.

Obviously, it exceeds the design of the native driver, and we try to
extend the length of a single data packet to 16 bytes in patch(1/2).

I apologize that this radical change may not be the best way to go, and
I will try to rewrite this section if there are better suggestions.

Thanks.
