Seriously ? I was responding to the whole comment, don't be so pedantic

I have a device with this chip in it .. I would like that device not to
disappear from Linux .. Doing this puts an un-do burden on users
who would like to see this support go in, but if it's removed like this
that will never happen. No one has an much information on these chips as
Qualcomm .. It's not realistic that any user would be able to do a
lot without their support.. By allowing them to remove code for these
device it effectively ends and chance of them have more code support added..
Yet the devices exist in mass amounts.

To be honest your not an MSM maintainer, are there are political issue
related to this.. This isn't particularly technical because converting
these relatively simple platform to the device tree shouldn't be all
that difficult. To me Your involvement is puzzling .. Myself and my
co-maintainers need to be the ones discussing this..

G1 code is also getting removed in this series, and the code for this
creates a usable device .. The problem here is that you really can't
start randomly removing support for platforms that people have and want
them to continue working. We have a process for that, and typically user
objections weight heavily in that process (read, feature-removal-schedule.txt)
