The ESCR and OTAR registers are not present in all DU channels on Gen3 SoCs. ESCR only exists in channels that can be routed to an LVDS or DPAD, and OTAR in channels that can be routed to a DPAD. Skip writing those registers for other channels. This replaces the DU gen check, as Gen4 doesn't have LVDS or DPAD outputs.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
