Cool Pi GenBook works as a mother board connect with CM5 [0].

s/mother board/carrier board/

This can be changed to carrier board in next version。

s/CM5/GenM5/

In fact, the SOM is called CM5 always[0], even this laptop was
called cm5 laptop from the
very beginning of the design。
They just gave it a new name GenBook when it comes to crowdsupply.

The dtsi for CM5 is aready landing upstream,I inclulde it in the
current genbook dts。

Ah, that's quite interesting, it was probably renamed for marketing
purposes. Thanks for the clarification.

To add to the confusion, none of "GenBook", "CM5" or "GenM5" appear
on the labels found on the actual PCBs. [1] Instead, there are only
some rather generic terms.

Specification:
- Rockchip RK3588
- LPDDR5X 8/32 GB
- eMMC 64 GB
- HDMI Type A out x 1
- USB 3.0 Host x 1
- USB-C 3.0 with DisplayPort AltMode
- PCIE M.2 E Key for RTL8852BE Wireless connection
- PCIE M.2 M Key for NVME connection
- eDP panel with 1920x1080

This patch add basic support to bringup eMMC/USB HOST/WiFi
and can also drive a HDMI output with out of tree hdmi patches.

It would be better to split this into two files: a dtsi for the GenM5
system
on module, and a dts for the GenBook carrier board. That way, the
dts(i) files
would describe the actual hardware better.
