Enable Adaptive Sync SDP for Panel replay + auxless ALPM. First few patches are fixes in existing AS SDP enablement. Later patches add the support to send AS SDP for Panel replay with Link ON and with auxless ALPM (Link-Off).
I have mistakenly sent the series --in-reply-to <msg-id>. I will send the series again. Sorry for the confusion caused. :( Regards, Ankit
