[PATCH 0/6] Rename DTB overlay source files

[PATCH 0/6] Rename DTB overlay source files

[Andrew Davis]

Hello all,

This is a series based on my patch here[0]. As suggested by Rob
I've resurrected Frank's patch and appended it to mine as a series.

First patch here is my original patch, 3rd is Frank's patch but with
the unittest changes pulled out into the 2nd patch. That was re-worked
moving the source building macro into scripts/Makefile.lib.

Patches 4, 5, and 6 are an attempt at renaming all the existing DTB
overlays. Split out by platform so they could be taken by platform
maintainers or if easier ACK'd here and taken all together.

This should cover all the DTB overlays so we can remove the old .dts
rule for overlays and make .dtso the only supported way, let me know
if we want that this cycle and I can post that too.

Thanks,
Andrew

[PATCH 1/6] kbuild: Allow DTB overlays to built from .dtso named source files

[Andrew Davis]

Currently DTB Overlays (.dtbo) are build from source files with the same
extension (.dts) as the base DTs (.dtb). This may become confusing and
even lead to wrong results. For example, a composite DTB (created from a
base DTB and a set of overlays) might have the same name as one of the
overlays that create it.

Different files should be generated from differently named sources.
 .dtb  <-> .dts
 .dtbo <-> .dtso

We do not remove the ability to compile DTBO files from .dts files here,
only add a new rule allowing the .dtso file name. The current .dts named
overlays can be renamed with time. After all have been renamed we can
remove the other rule.

[PATCH 2/6] kbuild: Allow DTB overlays to built into .dtso.S files

[Andrew Davis]

DTB files can be built into the kernel by converting them to assembly
files then assembling them into object files. We extend this here
for DTB overlays with the .dtso extensions.

We change the start and end delimiting tag prefix to make it clear that
this data came from overlay files.

[PATCH 3/6] of: overlay: rename overlay source files from .dts to .dtso

[Andrew Davis]

From: Frank Rowand <frank.rowand@sony.com>

In drivers/of/unittest-data/:
   - Rename .dts overlay source files to use .dtso suffix.

Modify driver/of/unitest.c to use .dtbo.o based symbols instead of .dtb.o

[PATCH 4/6] arm64: dts: freescale: Rename DTB overlay source files from .dts to .dtso

[Andrew Davis]

DTB Overlays (.dtbo) can now be built from source files with the
extension (.dtso). This makes it clear the content of the file
and differentiates them from base DTB source files.

Convert the DTB overlay source files in the arm64/freescale directory.

[PATCH 5/6] arm64: dts: renesas: Rename DTB overlay source files from .dts to .dtso

[Andrew Davis]

DTB Overlays (.dtbo) can now be built from source files with the
extension (.dtso). This makes it clear the content of the file
and differentiates them from base DTB source files.

Convert the DTB overlay source files in the arm64/renesas directory.

Thanks a lot for picking this up!

Everything builds still fine, and the OF unit tests still run fine, so
Tested-by: Geert Uytterhoeven <geert+renesas@glider.be>

BTW, you missed the Smarthome-Wolf Pi433 overlay[1] and its
documentation[2] under drivers/staging/, but perhaps that was
intentional, as it is not tied into the build system?

Wasn't really sure about that one, but it seems simple enough to rename,
will add a patch for that in v2. Will also fix the wording in the last
3 patches as suggested.
