e1eeeae2bf Staging: mrst-touchscreen: fix channel allocation in the touch screen driver
the touch screen driver tries to find a range of free channels (which
are an array of bytes), by scanning for the "end of used channel" marker.
however it tries to be WAAAAY too smart and does 32 bit logic on 8 bit
quantities, and in the process completely gets it wrong
(repeatedly read the same register instead of incrementing in the loop,
assuming that if any of the 4 bytes in the 32 byte quantity is free,
all four are free, returning the channel number divided by 4 rather than
the actual first free channel number)

On the setting side, the same mistakes are made by and large; changed
this to just use the byte SCU write functions....

with these fixes we go from a completely non detected touchscreen to
something that appears to completely get detected.
(after also fixing the ordering issue that Jacobs patch should solve)

a4cff8b82a Staging: mid: Intel MID touch screen driver
Touchscreen driver used by intel mid devices. Some clean up by Alan Cox. This
driver is basically ready for upstreaming properly but is tied wrongly to the
SPI layer and needs firmware/SFI changes to fix that.
