Add support for generic electronic privacy screen properties, that can be added by systems that have an integrated EPS. Changes in v2 (Hans de Goede) - Create 2 properties, "privacy-screen sw-state" and "privacy-screen hw-state", to deal with devices where the OS might be locked out of making state changes - Write kerneldoc explaining how the 2 properties work together, what happens when changes to the state are made outside of the DRM code's control, etc. Changes in v3 (Hans de Goede) - Some small tweaks to the kerneldoc describing the 2 properties Changes in v4 (Hans de Goede) - Change the "Enabled, locked" and "Disabled, locked" hw-state enum value names to "Enabled-locked" and "Disabled-locked". The xrandr command shows all possible enum values separated by commas in its output, so having a comma in an enum name is not a good idea. - Do not add a privacy_screen_hw_state member to drm_connector_state since this property is immutable its value must be directly stored in the obj->properties->values array Signed-off-by: Rajat Jain <rajatja@google.com> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.com> Reviewed-by: Mario Limonciello <Mario.limonciello@dell.com> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Co-developed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211005202322.700909-2-hdegoede@redhat.com
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.
