HDMI 2.0 spec adds support for YCBCR420 sub-sampled output.
CEA-861-F adds two new blocks in EDID's CEA extension blocks,
to provide information about sink's YCBCR420 output capabilities.
These blocks are:
- YCBCR420vdb(YCBCR 420 video data block):
This block contains VICs of video modes, which can be sopported only
in YCBCR420 output mode (Not in RGB/YCBCR444/422. Its like a normal
SVD block, valid for YCBCR420 modes only.
- YCBCR420cmdb(YCBCR 420 capability map data block):
This block gives information about video modes which can support
YCBCR420 output mode also (along with RGB,YCBCR444/422 etc) This
block contains a bitmap index of normal svd videomodes, which can
support YCBCR420 output too.
So if bit 0 from first vcb byte is set, first video mode in the svd
list can support YCBCR420 output too. Bit 1 means second video mode
from svd list can support YCBCR420 output too, and so on.
This patch adds two bitmaps in display's hdmi_info structure, one each
for VCB and VDB modes. If the source is HDMI 2.0 capable, this patch
adds:
- VDB modes (YCBCR 420 only modes) in connector's mode list, also makes
an entry in the vdb_bitmap per vic.
- VCB modes (YCBCR 420 also modes) only entry in the vcb_bitmap.

V2: Addressed
Review comments from Emil:
- Use 1ULL<<i instead of 1<<i to make sure the output is 64bit.
- Use the suggested method for updating dbmap.
- Add documentation for YCBCR420_vcb_map to fix kbuild warning.
Review comments from Ville:
- Do not expose the YCBCR420 flags in uabi layer, keep it internal.
- Save a map of YCBCR420 modes for future reference.
- Check db length before trying to parse extended tag.
- Add a warning if there are > 64 modes in capability map block.
- Use y420cmdb in function names and macros while dealing with vcb
to be aligned with spec.
- Move the display information parsing block ahead of mode parsing
blocks.
V3: Addressed design/review comments from Ville
- Do not add flags in video modes, else we have to expose them to user
- There should not be a UABI change, and kernel should detect the
choice of the output based on type of mode, and the bitmaps.
- Use standard bitops from kernel bitmap header, instead of calculating
bit positions manually.
V4: Addressed review comments from Ville:
- s/ycbcr_420_vdb/y420vdb
- s/ycbcr_420_vcb/y420cmdb
- Be less verbose on description of do_y420vdb_modes
- Move newmode variable in the loop scope.
- Use svd_to_vic() to get a VIC, instead of 0x7f
- Remove bitmap description for CMDB modes & VDB modes
- Dont add connector->ycbcr_420_allowed check for cmdb modes
- Remove 'len' variable, in is_y420cmdb function, which is used
only once
- Add length check in is_y420vdb function
- Remove unnecessary if (!db) check in function parse_y420cmdb_bitmap
- Do not add print about YCBCR 420 modes
- Fix indentation in few places
- Move ycbcr420_dc_modes in next patch, where its used
- Add a separate patch for movement of drm_add_display_info()
V5: Addressed review comments from Ville:
- Add the patch which cleans up the current EXTENDED_TAG usage
- Make y420_cmdb_map u64
- Do not block ycbcr420 modes while parsing the EDID, rather
add a separate helper function to prune ycbcr420-only modes from
connector's probed modes.
V6: Rebase
V7: Move this patch after the 420_only validation patch (Ville)
V8: Addressed review comments from Ville
- use cea_vic_valid check before adding cmdb/vdb modes
- add check for i < 64 while adding cmdb modes
- use 1ULL while checking bitmap

(cherry picked from commit 832d4f2f41)
YCBCR420 modes are supported only on HDMI 2.0 capable sources.
This patch adds:
- A drm helper to validate YCBCR420-only mode on a particular
connector. This function will help pruning the YCBCR420-only
modes from the connector's modelist.
- A bool variable (ycbcr_420_allowed) in the drm connector structure.
While handling the EDID from HDMI 2.0 sinks, its important to know
if the source is capable of handling YCBCR420 output, so that no
YCBCR 420 modes will be listed for sources which can't handle it.
A driver should set this variable if it wants to see YCBCR420 modes
in the modedb.
V5: Introduced the patch in series.
V6: Squashed two patches (validate YCBCR420 and add YCBCR420
identifier)
V7: Addressed review comments from Vile:
- Move this patch before we add 420 modes from EDID.
- No need for drm_valid_cea_vic() check, function back to non-static.
- Update MODE_STATUS with NO_420 condition.
- Introduce y420_vdb_modes variable in this patch

CEA-861-F adds ycbcr capability map block, for HDMI 2.0 sinks.
This block contains a map of indexes of CEA modes, which can
support YCBCR 420 output also. To avoid multiple parsing of same
CEA block, let's parse the sink information and get this map, before
parsing CEA modes.
This patch moves the call to drm_add_display_info function, before the
mode parsing block.

(cherry picked from commit 0f0f870830)
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
- VIC for 4K modes for HDMI 1.4 sinks
- S3D information for S3D modes
As CEA-861-F has already defined VICs for 4K videomodes, this
patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
until the mode is 3D.

Under some circumstances the Frame Composer arithmetic unit can miss
an FC register write due to being busy processing the previous one.
The issue can be worked around by issuing a TMDS software reset and
then write one of the FC registers several times. After tested, the
number of iterations of RK3399/RK3328(v2.11a), RK3368(v2.01a),
RK3288(v2.00a) is one.
