Change subject: bts-trx: Implement ramp up/down during ADM state change
......................................................................


Patch Set 5:

With this new version of the patch I can get CS channels/TS working again after "rf_lock 0", but PDCH doesn't work again, and I strangely receive a lot of RACH requests on that TS...

And also poll timeouts:

So I guess I'm missing some part to re-activate PDCH.
