[PATCH v2 3/9] bus: mhi: Match devices exposing the protocol on the SAHARA channel

From: Kishore Batta

Date: Sat Mar 07 2026 - 06:42:33 EST


Some Qualcomm devices expose the Sahara protocol on a generic SAHARA MHI
channel rather than a QAIC specific channel name. As a result, the sahara
driver does not currently bind to such devices and never probes.

Extend the MHI device ID match table to also match the SAHARA channel
name. This allows the Sahara protocol driver to bind to devices that
expose the protocol directly on a standard sahara MHI channel.
