Linux kernel source tree

At least for panel-bridges, the atomic_enable call is defined as being called right after the preceding element in the display pipe is enabled. It is also stated that "The bridge can assume that the display pipe (i.e. clocks and timing signals) feeding it is running when this callback is called" This means the DSI controller driving this display would have already switched over to video-mode from command mode and thus dcs functions should not be called anymore at this point. This caused a non-working display for me, when trying to enable the rk3576 dsi controller using a display using this controller. Therefore move the display_on/off calls the more appropriate prepare/unprepare callbacks.

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 reStructuredText 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.
