[PATCH v2 5/9] bus: mhi: Add QDU100 firmware image table

From: Kishore Batta

Date: Sat Mar 07 2026 - 06:44:52 EST


Add firmware image table support for the Qualcomm QDU100 device to the
sahara protocol driver.

The QDU100 device expose the Sahara protocol directly on the SAHARA MHI
channel. Select the appropriate firmware image table based on the matched
MHI channel, allowing the driver to load QDU100 firmware images without
requiring device specific client drivers or additional registration
mechanisms.

This change integrates QDU100 support into the existing probe time
variant selection logic and does not affect the behavior of existing AIC
devices.
