AR6002 support in ath6kl driver

Greetings,

So I have recently been asked to begin supporting an AR6002 platform.
Currently it is using the Atheros ar6000 (v 2.1.2) driver. I see that
the ar6kl driver only supports the AR6003 and was wondering if there
was some technical reason that support for the AR6002 was dropped in
the up-streaming process? If not, would AR6002 support be welcomed in
the mainstream driver should I decide to attempt the endeavor of
porting/adding into the ath6kl driver? Finally, could I expect any
support from the ath6kl developers troubleshooting issues that would
inevitable arise along the way?

V/r,
Daniel Smith
