drm/hdcp: update content protection property with uevent
drm function is defined and exported to update a connector's content protection property state and to generate a uevent along with it. Pekka have completed the Weston DRM-backend review in https://gitlab.freedesktop.org/wayland/weston/merge_requests/48 and the UAPI for HDCP 2.2 looks good. The userspace is accepted in Weston. v2: Update only when state is different from old one. v3: KDoc is added [Daniel] v4: KDoc is extended bit more [pekka] v5: Uevent usage is documented at kdoc of "Content Protection" also [pekka] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/320963/?series=57232&rev=14
