In order to prevent some pixels getting stuck in an unflushable FIFO on bcm2711, we need to enable the HVS, the pixelvalve (the CRTC) and the HDMI controller (the encoder) in an intertwined way, and with tight delays. However, the atomic callbacks don't really provide a way to work with either constraints, so we need to roll our own callbacks so that we can provide those guarantees. Since those callbacks have been implemented and called in the CRTC code, we can just implement them in the HDMI driver now.

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.
