[PATCH 1/3] dt-bindings: vendor-prefixes: Add yet another for ST-Ericsson

[PATCH 1/3] 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 2/3] 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.

[PATCH 3/3] dt-bindings: arm: Document compatibles for Ux500 boards

[Stephan Gerhold]

The device-specific compatible values used by the Ux500 boards
were not documented so far. Add a new simple schema to document them.

Please add 'deprecated: true' to the 2 that are not preferred. Looks
like 'stericsson' should be preferred as it is used the most.
