Hi Dmitry,
I added the review about 'ARRAY_SIZE(tegra124_device_configs)'.
Except for this, it looks good to me.

Replace printk() with pr_err(), pr_warn() and pr_info(). Do not split long
strings, for easier grepping. Use `__func__` whenever applicable.
fbcon_prepare_logo() has more than one callers, use "fbcon_prepare_logo:"
instead of "fbcon_init:", for less confusion.

Hi Dmitry,
This patch contains the three features as following:
1. Use interconnect interface for controlling the clock instead of
controlling it direclty
2. Use EMC_STAT instead of IMC_STAT
3. Change polling_interval and upthreshold for more fast responsiveness
I think you need to make the

The horizontal resolution (640) for the TT High video mode (1280x960) is
definitely bogus. While fixing that, correct the timings to match the
TTM195 service manual.

Untested on actual hardware, hence the RFC.

- Use correct base.

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:
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 helper functions to
From: Swati Sharma
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
This patch adds support for configuring a PCON device,
connected as a DP branched device to enable FRL Link training
with a HDMI2.1 + sink.
v2: Fixed typos and addressed other review comments from Uma Shankar.
-changed the commit message for better clarity (Uma Shankar)
-removed unnecessary
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
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
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,
The caps are read during dfp update and can later be used to get the
PPS parameters for PCON-HDMI2.1 sink pair. Which inturn will be used
to take a call to
