From 953a457e50958494cfa90b41a13c26e9fb04195c Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 29 Jan 2016 07:00:37 -0200 Subject: [media] v4l2-mc.h Add pads for audio and video IF-PLL decoders The audio and video IF-PLL decoders have one sink and one source PAD. Add macro names for those pads and describe what kind of signals are represented at such pads.
