Can anyone give the attachment 144237 a try and let me know the result?
And if the issue still exists, please apply attachment 144238 also which can
provide more debug outputs.

Add a new optional renesas,companion property to point to the companion
LVDS encoder. This is used to support dual-link operation where the main
LVDS encoder splits even-numbered and odd-numbered pixels between the
two LVDS encoders.
The new property doesn't control the mode of operation, it only
Extend the drm_bridge_timings structure with a new dual_link field to
indicate that the bridge's input bus carries data on two separate
physical links. The first use case is LVDS dual-link mode where even-
and odd-numbered pixels are transferred on separate LVDS links.

Enable and connect the second LVDS encoder to the second LVDS input of

Set a drm_bridge_timings in the drm_bridge, and use it to report the
input bus mode (single-link or dual-link). The other fields of the
timings structure are kept to 0 as they do not apply to LVDS buses.

In dual-link LVDS mode, the LVDS1 encoder is used as a companion for
LVDS0, and both encoders transmit data from DU0. The LVDS1 output of DU1
can't be used in that case, don't create an encoder and connector for
it.

The THC63LVD1024 LVDS decoder can operate in two modes, single-link or
dual-link. In dual-link mode both input ports are used to carry even-
and odd-numbered pixels separately. Document this in the DT bindings,
along with the related rules governing port and usage.

Hello everybody,
This patch series implements support for LVDS dual-link mode in the
R-Car DU and R-Car LVDS encoder drivers, and well as in the thc63lvd1024
LVDS decoder driver.
LVDS dual-link is a mode of operation where two individual LVDS links
are operated together to carry even- and odd-num

Currently the source code is compiled using hard-coded values
from CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK. This patch allows this
clock divider value to be moved to the device tree and be changed
without having to recompile the kernel.

The variable actual_clock is being initialized however this is never
read and later it is being reassigned to a new value. The initialization
is redundant and hence can be removed.
