I've also just stumbled onto the issue of recent uboots not booting
on rk3288. While your patch seems to have reached patchwork, somehow
the u-boot list seems to have lost it - as it's neither in public
archives nor in my inbox it seems.

Applying the patch does not make my board (phycore-rk3288 in this case)
get farther though - I'll investigate more.


But it looks like we should be having the same issue in the kernel, just
never triggered it, as the gpio0 are of more esotheric uses normally.

Anyway, I'm wondering if defining IOMUX_WRITABLE_32BIT alone
wouldn't be enough and use that for iomux, pull and drv, similar to
what we do for the pull/drv register source already.

That way we could refrain from introducing DRV_TYPE_WRITABLE_32BIT
and PULL_TYPE_WRITABLE_32BIT .
