27e3b6298aa3 drm/edid: Add additional HFVSDB fields for HDMI2.1
-:60: WARNING:FROM_SIGN_OFF_MISMATCH: From:/Si
HDMI2.1 PCON advertises Max FRL bandwidth supported by the PCON and
by the sink.
This patch captures these in dfp cap structure in intel_dp and uses
these to prune connector modes that cannot be supported by the PCON
and sink FRL bandwidth.
v2: Addressed review comments from Uma Shankar:
-tweaked
When a source supporting DSC1.1 is connected to DSC1.2 HDMI2.1 sink
via DP HDMI2.1 PCON, the PCON can be configured to decode the
DSC1.1 compressed stream and encode to DSC1.2. It then sends the
DSC1.2 compressed stream to the HDMI2.1 sink.
This patch configures the PCON for DSC1.1 to DSC1.2 encod
This patch adds functions to start FRL training for an HDMI2.1 sink,
connected via a PCON as a DP branch device.
This patch also adds a new structure for storing frl training related
data, when FRL training is completed.
v2: As suggested by Uma Shankar:
-renamed couple of variables for better clar
This patch adds registers for getting DSC encoder capability for
a HDMI2.1 PCon. It also addes helper functions to configure
DSC between the PCON and HDMI2.1 sink.

There are specific DPCDs defined for detecting link failures between
the PCON and HDMI sink and check the link status. In case of link
failure, PCON will communicate the same using an IRQ_HPD to source.
HDMI sink would have indicated the same to PCON using SCDC interrupt

The DP-HDMI2.1 PCON spec provides way for a source to set PPS
parameters: slice height, slice width and bits_per_pixel, based on
the HDMI2.1 sink capabilities. The DSC encoder of the PCON will
respect these parameters, while preparing the 128 byte PPS.

This patch adds support for configuring a PCON device,

This patch calls functions to check FRL training requirements
for an HDMI2.1 sink, when connected through PCON.
The call is made before the DP link training. In case FRL is not
required or failure during FRL training, the TMDS mode is selected
for the pcon.

This patch adds support to read and store the DSC capabilities of the
HDMI2.1 PCon encoder. It also adds a new field to store these caps,

This patch parses HFVSDB fields for DSC1.2 capabilities of an
HDMI2.1 sink. These fields are required by a source to understand the
DSC capability of the sink, to set appropriate PPS parameters,
before transmitting compressed data stream.

This patch parses MAX_FRL field to get the MAX rate in Gbps that
the HDMI 2.1 panel can support in FRL mode. Source need this
field to determine the optimal rate between the source and sink

The HDMI2.1 extends HFVSDB (HDMI Forum Vendor Specific
Data block) to have fields related to newly defined methods of FRL
(Fixed Rate Link) levels, number of lanes supported, DSC Color bit
depth, VRR min/max, FVA (Fast Vactive), ALLM etc.
This patch adds the new HFVSDB fields

Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata
E5 to DisplayPort_v2.0:
