Hi, trying the webmail reply for a first time. Be gentle.

Do we have a consensus about this?
After the "errno-drivers" patchset, DEV_* codes will be used only at
and 'arch' layers. Actually, all occurrences of DEV_* codes in board/ are
from pinmux drivers. These drivers are going to be landed in drivers/ soon
(patches are under review on gerrit) so they will already be replaced by -E*
codes. This means that only a few files from arch/ will be using DEV_* codes.
If we have a consensus, the next steps are:
1) Replace DEV_* occurrences in arch/ (and boards/ if applicable);
2) Deprecate DEV_* (just add a comment in device.h saying: DEV_* are deprecate,
use errno.h codes instead.
+1 I would argue this should step 1. This can be and should be merged in before the close of the release window this week. So get this done ASAP.
3) Remove DEV_* codes.
Since 3) might break external applications, we should apply it during a major
release I guess.
I'd wait until the start of the next release cycle to make this change. It will give a long window of opportunity to update.
