Add SpacemiT K1 USB3.0 host controller support | expand

Message

Ze Huang April 28, 2025, 7:38 a.m. UTC

This patchset adds initial support for the USB 3.0 Dual-Role Device (DRD)
controller[1] found in the SpacemiT K1 SoC. The controller is based on Synopsys
DesignWare Core USB 3 (DWC3) IP, which already has mainline driver support.

The DWC3 controller on SpacemiT K1 supports both Host and Device modes for
USB 3.0 and USB 2.0, including High-Speed, Full-Speed, and Low-Speed operations.

The PHY interfaces required for the K1 USB subsystem, PIPE3 (for USB 3.0)
and UTMI+ (for USB 2.0) have already been supported in a previous patchset[2].

This patchset is based on 6.15-rc1. Tested on BananaPi and Jupiter board.

Changes in v2:
- dt-bindings:
  - add missing 'maxItems'
  - remove 'status' property in exmaple
  - fold dwc3 node into parent
- drop dwc3 glue driver and use snps,dwc3 driver directly
- rename dts nodes and reorder properties to fit coding style
