The DesignWare controller provides hardware support for HDR-BT transfers, but the current driver only supports SDR transfers. This limitation prevents users from utilizing the higher throughput capabilities available on supported hardware. Patch Overview: 1. Add HDR-BT capability in the I3C framework. 2. Implement HDR-BT operation in the DesignWare master driver. Dineshkumar Parameswaran.
