[PATCH 00/13] ARM: ux500: Misc Device Tree patches

[Lee Jones]

In this patchset we:

1. Remove nodes which aren't pertinent to Snowball from its DTS file
2. Provide ST-Ericsson's DTS[I] files with a ste-* prefix
3. Remove the old u9540.dts file 

[PATCH 01/13] ARM: ux500: Remove Toshiba TC35892 I/O Expander's DT entry from Snowball's DTS

[Lee Jones]

It doesn't exist on this development board.

[PATCH 03/13] ARM: ux500: Remove Snowball DTS entry for TPS61052 chip

[Lee Jones]

TPS61052 is a; boost converter, LED driver, LED flash driver and
simple GPIO pin chip. It has no use here however, as it is not
found on the Snowball development board.

Grmbl, grmbl, grmbl. This now breaks any script that knows to use
snowball.dtb. :(

It's good to get the prefixes added, but it's annoying to have to deal
with both during an overlap period. Maybe generate both dtb filenames
for a while but rename the source?

How would you create both DTB files from one DTS file?

Surely they only solution would be to maintain both snowball.dts and
ste-snowball.dts at the same time, which doesn't sound logical at all.

Why can't you do as Linus and I have done and just change your script?

Hm I had the same problem but changed my Makefile
(scripts are too simple for me) like this:

 dtb            := $(build_dir)/arch/arm/boot/dts/ste-hrefv60plus.dtb
+fallbackdtb    := $(build_dir)/arch/arm/boot/dts/hrefv60plus.dtb
(...)
-       cat $(dtb) >> $(output_dir)/zImage
+       if [ -f arch/arm/boot/dts/hrefv60plus.dts ] ; then \
+           cat $(fallbackdtb) >> $(output_dir)/zImage ; echo "fallback" ; \
+       else \
+           cat $(dtb) >> $(output_dir)/zImage ; \

Sure, working around it is trivial. I just did a:
   - at cp $</arch/arm/boot/dts/ste-snowball.dtb $</arch/arm/boot/dts/snowball.dtb

But the point is that everybody needs to do something like that now,
which is unfortunate.

Well with only ~5 active users it's probably not that much of a big
deal anyway, but I'm still interested to know what the alternative is?

This must have been a merge error. There was a patch which renamed the
u9540.dts to ccu9540.dts, however the u9540.dts was reincarnate with
the same patches which created it in the first place. Let's kill it
once and for all.

I applied all the rename patches but it appears they were never
really tested, so I made this patch fixing all the bugs they introduced.
(Quicker than iterating the patch set.)
