Christoph Niedermaier 43dcd41080 drm/imx: parallel-display: Remove bus flags check in imx_pd_bridge_atomic_check()
[ Upstream commit 6061806a86 ]

If display timings were read from the devicetree using
of_get_display_timing() and pixelclk-active is defined
there, the flag DISPLAY_FLAGS_SYNC_POSEDGE/NEGEDGE is
automatically generated. Through the function
drm_bus_flags_from_videomode() e.g. called in the
panel-simple driver this flag got into the bus flags,
but then in imx_pd_bridge_atomic_check() the bus flag
check failed and will not initialize the display. The
original commit fe141cedc4 does not explain why this
check was introduced. So remove the bus flags check,
because it stops the initialization of the display with
valid bus flags.

Fixes: fe141cedc4 ("drm/imx: pd: Use bus format/flags provided by the bridge when available")

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.
