Subject: [PATCH 2/6] dt-bindings: serdev: ngsm: Add binding for serdev-ngsm
Date: Thu, 30 Apr 2020 10:46:11 -0700
Message-ID: <20200430174615.41185-3-tony@atomide.com> (raw)
In-Reply-To: <20200430174615.41185-1-tony@atomide.com>

Add a binding document for a generic serdev-ngsm driver that can be
used to bring up TS 27.010 line discipline with Linux n_gsm support
on a serial port.

As the Motorola Mapphone modems require some custom handling, they
are handled with a separate compatible.

Let's also add vendor string for ETSI as we're using a ETSI 3GPP
TS 27.010 standard.
