It this case LDT can be useful. no sorry you miss the point here it's better to based your work on a clean driver so you can see how it's supposed to be written > > If you think that there is lack of subsystem driver template, please > write me.

I'm sorry but you code can not be useed as a recommandation for people to write new drivers. Read a mainline will be better and will show practice we use right now such as we de not use ifdef is the as muchas possible we use IS_ENABLED & co and for the UART Russel King the ARM Maintainer si currently reworking the tty API and I can point others suach PM, DT etc...
