[ Upstream commit 1d1f7b15cb9c11974cebfd39da51dc69b8cb31ff ] Do not create a custom directory in debugfs-root, but use the debugfs_init callback to create a custom directory at the given place for the bridge. The new directory layout looks like this on a Renesas GrayHawk-Single with a R-Car V4M SoC: /sys/kernel/debug/dri/feb00000.display/DP-1/1-002c Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com> Reviewed-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Douglas Anderson <dianders@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20250315201651.7339-2-wsa+renesas@sang-engineering.com Stable-dep-of: 55e8ff842051 ("drm/bridge: ti-sn65dsi86: Add HPD for DisplayPort connector type") Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
