Subject: [PATCH 00/11] USB: serial: mos7840: type detection and clean ups
Date: Thu,  7 Nov 2019 14:28:53 +0100
Message-ID: <20191107132904.2379-1-johan@kernel.org> (raw)

The mos7840 device-type detection is fragile and cannot generally be
relied upon (e.g. as recently reported for Moxa UPort 2210 which was
detected as a four-port device).

The first couple of patches adds support for encoding known chip
features in the device-id table, and documents the underlying
assumptions for the mcs7810-detection hack.

Turns out we have a lot of legacy cruft in this driver, and the
remaining patches rips that out.
