Hi Arnd,
Here you're dropping pxa variant support. For the currently
"partly" working
boards in devicetree, such a zylonite, this will break their
current support.
For example the zylonite I have which is working on DT has a
pxa310 variant.
The cm-x300, which also works in DT, has a pxa320 variant.
What these boards need is their IO mappings and cpufreq to still
work after
your serie in DT. What bothers me are the changes to :
- drivers/clk/pxa/clk-pxa3xx.c
- drivers/cpufreq/pxa3xx-cpufreq.c
Here the clock changes will probably remove the clock provided to
specific
pxa310/pxa320 drivers for example.
I don't know how you want to proceed, yet this change will break
some pxa3xx
platforms.
Cheers.

Hi Robert,
Thanks for pointing this out, I thought that I had caught
all the missing dependencies ones after you pointed out
the AC97_BUS_NEW that I fixed in patch 14.
From what I can tell, commit b5aaaa666a85 ("ARM: pxa: add
Kconfig dependencies for ATAGS based boards"), the
PXA310/PXA320 DT support became dead code because
MACH_PXA3XX_DT only selects CPU_PXA300, so if it worked
before that commit, it now needs CONFIG_UNUSED_BOARD_FILES
and CONFIG_EXPERT as well as enabling one of the legacy
board files with the corresponding chip support.
If that's all you think is missing, I can add this
trivial patch as well and rework the series to not
drop code that depends on PXA310/PXA320:
--- a/arch/arm/mach-pxa/Kconfig
+++ b/arch/arm/mach-pxa/Kconfig
@@ -45,6 +45,8 @@ config MACH_PXA27X_DT

bool "Support PXA3xx platforms from device tree"

+ select CPU_PXA310
+ select CPU_PXA320
select PINCTRL
select POWER_SUPPLY

Can you have a look at the other patches to see if there
are more removed drivers or platform bits that are currently
dead code but are actually required?

I've put this in a separate branch now and will submit
it as a bugfix along with two other patches for issues
I found while testing omap1.
I've dropped the pxa310/320 removal now, but kept
the pxa93x removal, since that has no DT support at
all and remains dead code.

Yes, I've been through your whole serie and that's the
last thing I have identified. I've read carefully all the
patches now, and the whole serie looks good to me.
So with this patch and keeping the clocks and cpufreq
parts for pxa3*0, you can add everywhere my :
