Tvrtko: thanks a lot for your effort and dumps coming from fglrx.
What I can say now: it seems fglrx is using the same registers
(EVERGREEN_AUDIO_PLL1_MUL and EVERGREEN_AUDIO_PLL1_DIV) for your card.
However:
1) radeon uses 480'000 for MUL
2) fglrx uses 960'000 for MUL
On the other hand fglrx uses 0x72 instead of 0x71 for EVERGREEN_AUDIO_PLL1_UNK.
Maybe that 0x2 is some DIV? Maybe it tells GPU to take 960'000 and divide it by
2?
I've to investigate meaning of the register, but you gave me a track to follow,
thanks a lot for your effors! I'll take a look on that after my vacations (next
week).
