Subject: [PATCH 1/2] dt-bindings: arm: amlogic: add GXLX/S905L/p271 reference board

Add support for an Amlogic GXLX based S905L SoC and P271 reference
design board. The S905L is a low-cost design similar to the P281
(S905W) and is similarly derived from P212 (S905X). However S905L
omits support for the VP9 codec and uses Mali 450-MP2 (not MP3).

Subject: [PATCH 2/2] arm64: dts: meson: add GXLX/S905L/p271 support

Add a device-tree for the GXLX Amlogic P271 (S905L) reference design
board. This is a low-cost design similar to P281 (S905W) but with
silicon differences to omit VP9 and use Mali 450-MP2 (not MP3). The
SoC is marked with S905L and "2" (believed to denote MP2) resulting
in chip distributor stock lists and Android STB marketing sometimes
describing it as an S905L2 chip.

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

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.11/arm64-dt)

[1/2] dt-bindings: arm: amlogic: add GXLX/S905L/p271 reference board

https://git.kernel.org/amlogic/c/f6386b5afa81724164263c30c48de733e0aab74c

These changes has been applied on the intermediate git tree [1].

The v6.11/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
