drm/dsc: Add helpers for DSC picture parameter set infoframes
According to Display Stream compression spec 1.2, the picture parameter set metadata is sent from source to sink device using the DP Secondary data packet. An infoframe is formed for the PPS SDP header and PPS SDP payload bytes. This patch adds helpers to fill the PPS SDP header and PPS SDP payload according to the DSC 1.2 specification. v7: * Use BUILD_BUG_ON() to protect changing struct size (Ville) * Remove typecaseting (Ville) * Include byteorder.h in drm_dsc.c (Ville) * Correct kernel doc spacing (Anusha) v6: * Use proper sequence points for breaking down the assignments (Chris Wilson) * Use SPDX identifier v5: Do not use bitfields for DRM structs (Jani N) v4: * Use DSC constants for params that dont change across configurations v3: * Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst (Daniel Vetter) v2: * Add EXPORT_SYMBOL for the drm functions (Manasi) Cc: dri-devel@lists.freedesktop.org Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Acked-by: Harry Wentland <harry.wentland@amd.com> Reviewed-by: Anusha Srivatsa <anusha.srivatsa@intel.com> Acked-by: Sean Paul <seanpaul@chromium.org> (For merging through drm-intel) Link: https://patchwork.freedesktop.org/patch/msgid/20181127214125.17658-5-manasi.d.navare@intel.com
