The adv7842 driver didn't support EDIDs of 3 or 4 blocks, even though the hardware supports this. It is a bit more complicated due to the fact that the adv7842 can expose two EDIDs: one digital, one analog, for DVI-I connectors. In that case the VGA_EDID_ENABLE bit is set and blocks 0 and 1 of the EDID eeprom are used for the DVI-D part and block 2 is used for the DVI-A part of the DVI-I connector.

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.
