We now have a pinctrl driver for arch-mvebu. It supports kirkwood out
of the box. Allow ARCH_KIRKWOOD to select it, and make ARCH_KIRKWOOD
select it. This then allows the convertion of board-*.c files away
from MPP to pinctrl in DT, before they get moved over into mach-mvebu.

Russell just spent the end of the release cycle sorting all of these
in alphanumeric order, so keep to that. (Move above
PLAT*)
Once they look OK I'd like to get ACKs from one of the ARM
SoC maintainers so I can merge this set through the
pinctrl tree.
Yours,
Linus Walleij

Linus Walleij has accepted a patch I have sent yesterday evening that
makes PINCTRL_MVEBU available for all PLAT_ORION platforms, so this
chunk is no longer needed.

This GPIO driver is generic to all Marvel Orion/XP/370 SoCs. Allow
Kirkwood to enable and use it. Fix the kirkwood DT to pass the
expected properties and remove the old gpio probing code.

Should we turn the depends on ARCH_MVEBU into a depends on PLAT_ORION,
like I did for the pinctrl driver (patch accepted by Linus Walleij
yesterday) ? I think the dependency on ARCH_MVEBU was making too much
of a shortcut, by assuming that we would very quickly move everybody
into mach-mvebu. As we rather decided to move gradually
mach-{kirkwood,dove,orion5x,mv78xx0} to those infrastructure while
keeping them in their respective directories, I think a dependency on
PLAT_ORION is more appropriate here.
Best regards,
Thomas

Since 3.7 readl/writel require register addresses to be const void*
instead of unsigned int. The register addresses are converted using
IOMEM() and offsets are added instead of OR'ed.
Also a workaround for the pdma clock is added, that is required as
there is still no DT clock provider available on Dove.

So essentially two unrelated patches squashed into one, and I
would apply the first one right off but now the clock change makes
me hesitate.

This is a horrible hack. But if the Marvell people agree about

Unfortunately, it is. This is an chicken-egg-problem here, no
DT clk-provider, no clocks properties..
While writing pinctrl-dove I was planing to enable it after
the clock provider but with Andrew pushing forward - for a good
reason - there comes the trouble ;)
I don't like the hack either but the clk-gate is there and
if I don't enable it pinctrl-dove will hang the SoC.
I have a clk-dove DT clk-provider in my pocket somewhere but
didn't find the time to prepare it for posting..

Then let's split out the dove-pinctrl patches until you have that series
ready.

Allow ARCH_DOVE to select pinctrl-mvebu with support for Dove SoC.
With the now enabled pinctrl driver also add the corresponding DT node
to Dove DT.

The MVEBU driver is generic to all Marvell Orion/XP/370 SoCs. Allow
Dove DT to enable and use it. Also fix dove DT to pass the expected
properties and add gpio aliases.
