[Chanho Min]

This patch series adds initial device tree support for the LG1215
TV SoC and its reference board.

Series overview:
  1/3 - dt-bindings: vendor-prefixes: Add 'lge' prefix for LG Electronics
  2/3 - dt-bindings: arm: lge: Add compatible for LG1215 SoC and ref board
  3/3 - arm64: dts: lg: Initial support for LG1215 SoC and reference board

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

[Chanho Min]

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'.

[PATCH 2/3] dt-bindings: arm: lge: Add compatible for LG1215 SoC and reference board

[Chanho Min]

Add compatible strings for the LG1215 SoC and its reference board
(lge,lg1215 and lge,lg1215-ref).

This SoC is the next SoC following the LG1313 series, developed
by LG Electronics.

[PATCH 3/3] arm64: dts: lg: Initial support for LG1215 SoC and reference board

[Chanho Min]

Add initial device tree support for LG Electronics LG1215 SoC
and its reference development board.

This patch introduces:
 - lg1215.dtsi : SoC level device tree include file
 - lg1215-ref.dts : Reference board specific file
 - Makefile update to build lg1215-ref.dtb

Currently supported minimal hardware description:
 - Quad ARM Cortex-A78 CPU
 - gic-400 interrupt controller
 - ARMv8 architected timer
 - pmu (Performance Monitoring Unit)
 - pl011 UARTs
 - pl080 DMA controller
 - sp804 timers, sp805 watchdog timers
 - Generic DWMAC ethernet controller

This is the minimal initial bring-up version. More peripherals (mmc, gpio,
pinctrl, etc.) will be added in follow-up patches.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20260108 (best guess, 2/3 blobs matched)
 Base: tags/next-20260108 (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

No, this makes no sense, that's not a bus or any sort of device. Drop
entire node.

I don't think this validates.

Also, you really should follow DTS coding style.

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

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.

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