In order to readout DP SDPs (Secondary Data Packet: DP HDR Metadata
Infoframe SDP, DP VSC SDP), it refactors handling DP SDPs codes.
It adds new compute routines for DP HDR Metadata Infoframe SDP
and DP VSC SDP.
And new writing routines of DP SDPs (Secondary Data Packet) that uses
computed configs.
New reading routines of DP SDPs are added for readout.
It adds a logging function for DP VSC SDP.
When receiving video it is very useful to be able to log DP VSC SDP.
This greatly simplifies debugging.
In order to use a common VSC SDP Colorimetry calculating code on PSR,
it uses a new psr vsc sdp compute routine.
v2: Minor style fix
v3:
- Add a new drm data structure for DP VSC SDP
- Replace a structure name to drm_dp_vsc_sdp from intel_dp_vsc_sdp
- Move logging functions to drm core [Jani N]
And use drm core's DP VSC SDP logging function
- Explicitly disable unused DIPs (AVI, GCP, VS, SPD, DRM. They will be
used for HDMI), when intel_dp_set_infoframes() function will be called.
v4:
- Use struct drm_device logging macros
- Rebased
v5:
- Add disabling DIPs(Data Island Packets) when LSPCON is used
When LSPCON is used, DIPs(Data Island Packets of DP or HDMI) will not
be used. Therefore it explicitly disables DIPs on encoder->pre_enable
callback.
- Use intel_de_*() functions for register access
- Add warning where a bpc is 6 and a pixel format is RGB.
- Addressed review comments from Uma
Add kernel docs for added data structures
Rename enum dp_colorspace to dp_pixelformat
Polish commit message and comments
Combine the if checks of sdp.HB2 and sdp.HB3
Add 6bpc to packining and unpacking of VSC SDP
