This is a preparation patch set for MST Panel Replay.
In case of MST Panel Replay we may have several CRTCs on single
pipe. There CRTCs representing virtual devices within e.g. docking
station. All these virtual devices has their own DPCD registers
containing their Panel Replay capability information. These needs to
be taken into account when computing used Panel Replay state. Due to
this we can't continue having only sink capabilities stored in struct
intel_dp.
This patch set is moving Panel Replay capabilities into struct
intel_connector to make them available for Panel Replay CRTC state
computation.
v2:
- use __le16 for two byte values in dpcd
- use sizeof instead of hardcoded size in reading dpcd
- drop unnecessarily passing intel_dp pointer
- inline simple helpers
- use intel_dp_attached_dp instead of passing as a parameter
- move pr/psr_dpcd into *_caps substruct
- add FIXME
- extra w/s removed
