[PATCH 0/2] i3c: master: dw-i3c-master: HDR-BT support

From: Dineshkumar Parameswaran

Date: Tue Oct 13 2026 - 04:06:26 EST


Hello,

This series adds HDR-BT (High Data Rate - Bulk Transport)
support to the Synopsys DesignWare I3C master driver.

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.
