One other thing.  Are the gpio's handled by Pavel's driver actually from the
MSM chip or from an external CPLD?  The registers are all defined as:

+               .reg = reg_num + DREAM_CPLD_BASE,

If they are external from the MSM chip this driver should probably be renamed
to something more appropriate since it is probably dream specific and not
generic to the msm architecture.

These are board specific gpios. I think it would be less confusing if
the msm gpio support was added first.

I did not see msm-generic gpios in the trees, where are they? What is
connected over them?

Did you look at arch/arm/mach-msm/gpio.[ch] ? It looks like there some
idle related code in there, and "SMEM" is connected through that code.
(unless I'm looking at an older tree.)

Aha, I see... more gpios. No wonder I had problems with MMC and
framebuffer....
