During board bringups its useful to have a DSI test pattern generator to isolate a DPU vs a DSI issue and focus on the relevant hardware block. To facilitate this, add an API which triggers the DSI controller test pattern. The expected output is a rectangular checkered pattern. This has been validated on a single DSI video mode panel by calling it right after drm_panel_enable() which is also the ideal location to use this as the DSI host and the panel have been initialized by then. Further validation on dual DSI and command mode panel is pending. If there are any fix ups needed for those, it shall be applied on top of this change. Changes in v2: - generate the new dsi.xml.h and update the bitfield names Signed-off-by: Abhinav Kumar <abhinavk@codeaurora.org> Link: https://lore.kernel.org/r/1626922232-29105-2-git-send-email-abhinavk@codeaurora.org Reviewed-by: Stephen Boyd <swboyd@chromium.org> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Rob Clark <robdclark@chromium.org> |

README
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.
