Commit Message

Imre Deak Nov. 7, 2022, 5:09 p.m. UTC 
Starting with TGL eDP is supported on ports B+ (besides port A), so make
sure DC states are not blocked on any such ports. For this add an
AUX_IO_<port> power domain for each port with eDP support. These domains
similarly to AUX_IO_A enable only the AUX_IO_<port> power well for an
enabled port, whereas the existing AUX_<port> domains enable both the
AUX_IO_<port> and the DC_OFF power wells as required by DP AUX transfers.

v2: (Ville)
- Split the change using AUX vs. AUX_IO on port A to a separate patch.
- Select AUX_IO vs. AUX based on crtc_state->has_psr instead of
  is_edp().
