From: Shane Parslow Date: Sat, 29 Oct 2022 09:03:56 +0000 (-0700) Subject: net: wwan: iosm: add rpc interface for xmm modems X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d08b0f8f46e45a274fc8c9a5bc92cb9da70d9887;p=linux.git net: wwan: iosm: add rpc interface for xmm modems Add a new iosm wwan port that connects to the modem rpc interface. This interface provides a configuration channel, and in the case of the 7360, is the only way to configure the modem (as it does not support mbim). The new interface is compatible with existing software, such as open_xdatachannel.py from the xmm7360-pci project [1].
