While cleaning up the descriptions of the delay for eDP panels I realized that we'd have a bug if any panels need the "prepare_to_enable" but HPD handling isn't happening in the panel driver. Let's put in a stopgap to at least make us not violate timings. This is not perfectly optimal but trying to do better is hard. At the moment only 2 panels specify this delay and only 30 ms is at stake. These panels are also currently hooked up with "hpd-gpios" so effectively this "fix" is just a theoretical fix and won't actually do anything for any devices currently supported in mainline.

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.
