Has anyone ported the MSMCE driver onto these patches yet? That would be a good check to make sure that rc-core has the necessary API. Cooler if it works both through LIRC and with an internal protocol decoder. The MSMCE driver in my old patches was very simplified, it removed about half of the code from the LIRC version. > > There are two patches on this series that deserve a better analysis, IMO: > > - V4L/DVB: ir-core: rename sysfs remote controller class from ir to rc > > As discussed, "IR" is not a good name, as this infrastructure could later > be used by other types of Remote Controllers, as it has nothing that > is specific to IR inside the code, except for the name.
