I had a comple minor comments on specific patches, but the ordering of the series needs a little tweaking. It should be - core/driver changes [current 1-3/6 are ok] - remove usage from mach-omap2/serial.c (currently part of 4/6) - remove am33x DT usage (current 5/6 is ok) - remove entirely from omap_device (omap_device part of 4/6 and 6/6 should be combined) Kevin > The approach thought of is to modify the serial core/serial driver to bypass > runtime PM if the UART in contention is a console and we are using "no_console_suspend" > in our bootargs. > > While fixing the above issue, there are other cleanups also done as part of > this series which are no longer required.
