Subject: [RFC PATCH] ARM: omap2plus_defconfig: Switch over to using 8250 driver
Date: Fri, 10 Apr 2015 13:18:13 -0500	[thread overview]
Message-ID: <1428689893-14605-1-git-send-email-nm@ti.com> (raw)

8250 driver should be relatively feature complete. It can co-exist
with omap-serial driver, so just enable 8250 OMAP layer driver and
route all ttyOx references to ttySx through the standard 8250 driver
to ensure no breakage of userspace occurs.

Current upstream next-20150410 status: (all boards pass without this patch)
Test is a basic boot test (using omap2plus_defconfig ofcourse)..

Ofcourse:
[    0.001035] WARNING: Your 'console=ttyO0' has been replaced by 'ttyS0'
does not help userspace when they are not able to dynamically handle switch.

Just curious if folks feel we are ready for this switch yet...
