[PATCH v2 0/2] Add OrangePi 6 Plus board

[Gary Yang]

Patch 1: add compatible strings for OrangePi 6 Plus board
Patch 2: add dts file for OrangePi 6 Plus board

OrangePi 6 Plus board is powered by Cix Sky1. You could find brief
introduction for SoC and related boards at:
http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/details/Orange-Pi-6-Plus.html

Currently, to run upstream kernel at OrangePi 6 Plus board, you need to
use BIOS released by OrangePi, and add "clk_ignore_unused=1" at bootargs.

[PATCH v2 1/2] dt-bindings: arm: cix: add OrangePi 6 Plus board

[Gary Yang]

OrangePi 6 Plus adopts CIX CD8180/CD8160 SoC,
built-in 12-core 64-bit processor + NPU processor,
integrated graphics processor, equipped with 16GB/32GB/64GB
LPDDR5, and provides two M.2 KEY-M interfaces 2280 for NVMe SSD,
as well as SPI FLASH and TF slots to meet the needs of fast
read/write and high-capacity storage;

If there is going to be resend/new version, please re-wrap it.

Please wrap commit message according to Linux coding style / submission
process (neither too early nor over the limit):
https://elixir.bootlin.com/linux/v6.4-rc1/source/Documentation/process/submitting-patches.rst#L597

No need to resend just for this.
