Hans de Goede 476df59948 drm/simpledrm: Add "panel orientation" property on non-upright mounted LCD panels 
commit 94fa115f7b upstream.

Some devices use e.g. a portrait panel in a standard laptop casing made
for landscape panels. efifb calls drm_get_panel_orientation_quirk() and
sets fb_info.fbcon_rotate_hint to make fbcon rotate the console so that
it shows up-right instead of on its side.

When switching to simpledrm the fbcon renders on its side. Call the
drm_connector_set_panel_orientation_with_quirk() helper to add
a "panel orientation" property on devices listed in the quirk table,
to make the fbcon (and aware userspace apps) rotate the image to
display properly.

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.
