Working here on pandora too, applied on top of linux-next (did not
test suspend though).

Not caused by this patch, but the old problem where lower measurement
bits get lost is back - when I draw diagonal line it looks like
stairs. I think it's caused by OMAP SPI driver, CCing linux-omap.


          

Yes, it is OMAP spi driver issues, I have met the same problem before,
please refer to:
http://www.spinics.net/lists/arm-kernel/msg91538.html

you can apply this patch and test again.
        

It solves my issue, thanks

BTW I have done similar patch almost 2 years ago for exactly the same problem:
http://marc.info/?l=linux-omap&m=122565580616920&w=2
but then problem went away after random kernel update (from what I
remember), and my patch was no longer needed.

      

Really similar problem and similar solution, :-)
    

Let's get this fix into the mainline tree then. Jason, care to
refresh (it's wrapped at least) and then repost with the acks so
Grant can queue it up for the upcoming merge window?

OK, i will refresh it and re-post it to linux-spi and Grant.

Thanks,
Jason.
