[PATCH v4 2/3] riscv: dts: spacemit: k3-deepcomputing-fml13v05: add USB controller and USB phy support

[Sandie Cao]

Add USB device node (b, c, d) to DeepComputing FML13V05 board.
USB A works on otg mode, it isn't configured currently.
- 4 USB-C Ports
     - Port 1: PD 3.0 (65W Max), USB 3.2 Gen 1
     - Port 2: PD 3.0 (65W Max), USB 3.2 Gen 1, DP 1.4 (4K@60Hz)
     - Port 3 & 4: USB 3.2 Gen 1

This patch also enables usb2_host with a GL850G hub, which the commit
message doesn't mention.

Otherwise, LGTM.

Drop it, not really useful to mention there, irrelevant to this patch.

Currently, No USB A port support is merged in mainline code.
FYI, Chunyan submitted a patch for adding peripheral support of USB A.

For "Port X" here, is it a naming from FML13V05's schematic?
would be great to mention which specific USB 3.0 controller (Port B, C, D)
 of the SoC it connect to..

Is there any public schematic available for FML13V05? I guess there is
no CD pin (Card Detect pin)? as no "cd-gpios" property seen here

The above comment isn't really useful or even correct, I'd suggest
drop it.

"no-removable" property usually used for emmc chip soldered on board,
 so there is no way it can be physically removed.. check 
Documentation/devicetree/bindings/mmc/mmc-controller-common.yaml

For cases that no CD pin (or no GPIO CD pin) designed for SD card from
hardware schematic perspective, using "broken-cd" is a more proper way,
it will fallback to use poll mechanism to detect the card, please check
