Subject: [PATCH 0/5] Provide HDMI VSI & SPD InfoFrames to DW HDMI QP TX

This patch series provides the missing support for sending HDMI
Vendor-Specific Infoframes and Source Product Description InfoFrames in
dw-hdmi-qp library.

Additionally, it improves the existing AVI, DRM and Audio infoframes
handling by getting rid of some boilerplate and/or redundant code.
