[PATCH v1 0/2] Add OrangePi 6 Plus board

[PATCH v1 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 v1 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;

That's not a valid prefix. Where is it documented and how it looks there?

Why this cannot be part of enum with the first device? Creating a list
per device scales poorly.
