These match the spec. But to match the standard i915 convention they
should be called _AUD_PORT_EN_B_DBG etc. Same forthe chicken bit
register.
Actually they just match one version of the spec I had lying around.
Another versions says:
AUD_PORT_EN_B_DBG 0x62F20
AUD_PORT_EN_C_DBG 0x62F30
AUD_PORT_EN_D_DBG 0x62F34
That's it! Now finally I can hear the audio from DP3 with the
additional patch below.
Wow. Thanks Ville for looking into this, we could have lost a lot of
time. Do you happen to know if those previous values are due to poor
documentation or a different skew we'd need to support, e.g. with a
PCI-Id quirk?
At any rate, 2 days to get DP audio working is pretty nice, this was a
good week.
