[PATCH v4 0/2] Add DeepComputing FML13V05 board dts

[Sandie Cao]

This series updates Device Tree related files to introduce the
FML13V05 board from DeepComputing, which incorporates a Spacemit
K3 SoC.  This board is designed for use on the Framework Laptop 13
Chassis, which has (Framework) SKU FRANHQ0001.

The series is rebased on k1/dt-for-next.

v4:
- Patch 1:
  Add Acked-by Conor Dooley.
- Patch 2:
  Copyright begins from 2026.

v3:
rebased on k1/dt-for-next.
- Patch 1:
   Use formal format user name.
   Remove Reviewed-by Heinrich Schuchardt from internal system.
- Patch 2:
   Use formal format user name.
   Remove Reviewed-by Heinrich Schuchardt from internal system.
   Add uart0 pinctrl.

[PATCH v4 2/2] riscv: dts: spacemit: add DeepComputing FML13V05 board device tree

[Sandie Cao]

The FML13V05 board from DeepComputing incorporates a SpacemiT K3 RISC-V
SoC.It is a mainboard designed for the Framework Laptop 13 Chassis,
which has (Framework) SKU FRANHQ0001.

The FML13V05 board features:
- SpacemiT K3 RISC-V SoC
- LPDDR5 16GB or 32GB
- eMMC 32GB ~128GB (Optional)
- UFS 3.1 256G (Optional)
- QSPI Flash
- MicroSD Slot
- PCIe-based Wi-Fi
- 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 minimal device tree enables booting into a serial console with UART
output.
