[PATCH V2 0/2] Devicetree for board AN400 based Amlogic T7 SoC

[Xianwei Zhao]

Add the board AN400 tree bindings based Amloigc T7 SoC.

Add devicetree support for Amlogic AN400  board based T7 SoC.

Changes Since v1:
 -in memory node use properties "reg" instead of "linux,usable-memory"

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.6/arm64-dt)

[1/1] dt-bindings: arm: amlogic: add board AN400
      https://git.kernel.org/amlogic/c/015623ec05f96b1614ec2753d25f36743c17c530
[2/2] arm64: dts: add board AN400
      https://git.kernel.org/amlogic/c/6f048cc7a635b8736b4c7ae0e5230a92e3e648eb

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

The v6.6/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.
