Dave Stevenson ee1ca1aff6 drm: vc4: dsi: enable video and then retry failed transfers
The DSI block appears to be able to come up stuck in a condition where
it leaves the lanes in HS mode or just jabbering. This stops LP
transfers from completing as there is no LP time available. This is
signalled via the LP1 contention error.

Enabling video briefly clears that condition, so if we detect the
error condition, enable video mode and then retry.

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.
