[PATCH 0/4] arm64: dts: rockchip: Add HINLINK H66K/H68K

[Chukun Pan]

The HINLINK H66K and H68K are development boards with the Rockchip
RK3568 SoC. These boards are all SoM plus expansion board structures.

Both boards can be booted from eMMC or SD-card using the
U-Boot 2025.07 generic-rk3568 target.

The SoM board has CPU, RAM, eMMC and RK809 PMIC.
There is no schematic for this part.

The rest of the schematic can be found here:

It should be noted that there is a version of SeeedStudio called
LinkStar H68K, which is different from HINLINK H68K only in the shell.

The HINLINK H68K has two versions distinguished by the shell, and there
is no actual difference. This series is tested on H68K and H68K-V2.
