Hi folks, I've been toying with the idea of removing drivers/tty/serial/omap-serial.c since that's, to put it bluntly, an ungly copy of 8250 driver. The original concern was wrt suspend/resume but I think it'd be a far better approach to implement runtime PM in 8250 and write a rather small 8250-omap.c glue (much like 8250-acorn.c or 8250-dw.c) just to get the OMAP-specific details out of the way. The question I have is: omap-serial.c calls the serial devnodes ttyO\d, instead of ttyS\d so removing omap-serial.c would have a direct impact in userland. I wonder if it's an acceptable "regression" considering we'd be able to reuse 8250 gaining proper Flow Control support, proper DMA support, years and years of bug-fixes, etc. What do you guys say ? -- balbi -------------- next part -------------- A non-text attachment was scrubbed...
