I have this patch in my local tree for 2 monthes (see [1]). This is the patch
I'd rather have. I had not posted it as I didn't think the pinctrl work was over
yet. I know at least that pxa3xx is ready (as pinctrl-single should be used),
and I had not the time to create the map for pxa25x.

Once you are done, does that mean the plat-pxa/mfp.c stuff becomes
completely unused on pxa, or will it coexist with pinctrl?

At first it will coexist.
The main blocker so far I have are :
 - the pinconf in platform_data platform to define sleep state pin levels
   (aka. MFPR_LPM_DRIVE_LOW and MFPR_LPM_DRIVE_HIGH)
   I have [1], but it's not working yet, ie. upon entering suspend to RAM, the
   GPIO sleep registers are not programmed as expected.
 - all the pxa machine code have to be migrated from MFP to pinctrl

So it will take time.

Ok.

I'm asking because it seems that at that point, the entire plat-pxa
directory can be removed, with the dma.c and ssp.c files getting
moved to mach-pxa, and mfp.c moved to mach-mmp. :-)

dma.c will die soon enough anyway, ssp.c will move to mach-pxa indeed, and as
for mfp.c it requires a bit of work.

Sounds good.
