[PATCH 1/3] dt-bindings: vendor-prefixes: Add 'lge,*' for LG Electronics

Chanho Min posted 3 patches 1 month ago
There is a newer version of this series
[PATCH 1/3] dt-bindings: vendor-prefixes: Add 'lge,*' for LG Electronics
Posted by Chanho Min 1 month ago 
Currently 'lg,*' is used for LG Corporation, but LG Electronics uses
'lge' as vendor prefix for many of its device tree bindings
(lg1k SoCs, etc).

Add 'lge' vendor prefix entry to avoid confusion with 'lg'.

NAK, we have been there and I do not change my stance.

Unless you meant to add it because of EXISTING device trees (predating
commit fc75109288709 from Rob), then add with deprecated: true and don't
use it any new compatibles.

Hi Krzysztof

v2 will include:
 - "lg," prefix only ("lg,lg1215-ref", "lg,lg1215")
 - Drop "^lge,.*" from vendor-prefixes.yaml
 - dts coding style fixes in patch 3

Existing "lge," → "lg," conversion will be sent separately soon.

Thanks
Chanho Min

If you have existing compatibles released as ABI then they should stay
and you can document a deprecated lge prefix. But not for new devices.

One of many previous threads:

OK, I'll send the deprecated "lge," prefix documentation as a separate
follow-up patch.

Thanks,
