We were seeing a blank screen whenever Type1 content was played. This was due to extra timing which was taken as we had moved to remote read and writes previously for MST scenario, which in turn was done as we were not able to do direct read and writes to the immediate downstream device. The correct flow should be that we talk only to the immediate downstream device and the rest needs to be taken care by that device. With this patch series we move back to direct reads and writes, fix the fastset setting because of which direct reads and writes to HDCP related DPCD register stopped working, derive hdcp structure correctly and increase robustability if rxcaps HDCP capability reporting.
