Hi all, Here's a series of patches to add initial serdev support to n_gsm TS 27.010 line discipline.
This allows handling vendor specific protocols on top of TS 27.010 and allows creating simple serdev drivers where it makes sense. So far I've tested it with droid 4 for it's modem to provide char devices for AT ports, modem PM support, and serdev drivers for GNSS and Alsa ASoC. I'll be posting the related MFD, GNSS and Alsa ASoC drivers separately. For reference, the MFD driver is at [0], the GNSS driver at [1], and the Alsa ASoC driver at [2] below.
