[PATCH v3 0/3] Enable USB and SD for Deepcomputing FML13V05 board

[PATCH v3 0/3] Enable USB and SD for Deepcomputing FML13V05 board

[Sandie Cao]

This series updates Deepcomputing FML13V05 Device Tree: Add P1 PMIC 
regulator tree, add USB controller and USB phy, Enable SD card.

This series is rebased on next-20261030.

---
Changes in v3:
- Remove useless gpio header.
- Add Onboard SD Card comment.
- Link to v2: https://lore.kernel.org/all/20261020081633.3673704-1-
sandie.cao@deepcomputing.io/

Changes in v2:
- Remove usb3b, usb3c node define in k3.dtsi, it's already uploaded by 
other patch.
- Add phys and phys-name define for usb3b, usb3c, usb3d in 
k3-deepcomputing-fml13v05.
- Remove cd-gpios, use non-removable for sdhci0. 
- Remove vmmc-supply for sdhci0.
- Link to v1: https://lore.kernel.org/all/20260922110231.3426011-1-
sandie.cao@deepcomputing.io/

[PATCH v3 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

I believe this should be pmic@41
If it needs a label it could be p1: pmic@41 but the node name should be 
more descriptive.

This patch follows k3-pico-itx.dts, it uses p1@41. And k3-com260.dtsi uses pmic@41.
I will uses pmic@41 in next version.
