[PATCH v2 1/4] dt-bindings: vendor-prefixes: Add yet another for ST-Ericsson

[PATCH v2 1/4] dt-bindings: vendor-prefixes: Add yet another for ST-Ericsson

[Stephan Gerhold]

Unfortunately the vendor prefix for ST-Ericsson is used very
inconsistently. "ste," and "stericsson," are already documented,
but some things in the kernel use "st-ericsson," which is not
documented yet.

st-ericsson,u8500 is documented in bindings/arm/ux500/boards.txt,
and is used to match the machine code and the generic DT cpufreq
driver.

Add it to the list of vendor prefixes.

[PATCH v2 2/4] dt-bindings: vendor-prefixes: Deprecate "ste" and "st-ericsson"

[Stephan Gerhold]

Until now, device tree bindings for ST-Ericsson have been added
inconsistently with one of 3 possible vendor prefixes.

"stericsson" is the most commonly used vendor prefix,
so deprecate "ste" and "st-ericsson".

[PATCH v2 3/4] dt-bindings: vendor-prefixes: Add "calaosystems" for CALAO Systems SAS

[Stephan Gerhold]

The Snowball SBC supported by arch/arm/boot/dts/ste-snowball.dts
was made by CALAO Systems and uses the "calaosystems,snowball-a9500"
compatible. Prepare for documenting the compatible by adding
"calaosystems" to the list of vendor prefixes.

FWIW this is the byproduct of Ux500 being used as guinea pig
and shooting practice target in the early days of Arm Device Tree
support. I still think we got out pretty clean :D

I expect Rob to merge these patches as they are bindings-only,
alternatively I can take them in the Ux500 DTS pull request
for the next kernel cycle.

For this patch it would be easier if you take it through the Ux500 tree,
as I have another patch series that adds a new board to it.

The vendor-prefix patches are independent, so Rob can merge them if that
is easier?

OK I applied it for v5.6 on my ux500-dts branch.
