-Subject: [PATCH] drm/vc4: add iec958 controls to vc4_hdmi
-
-Although vc4 get an IEC958 formatted stream passed in from userspace
-the driver needs the info from the channel status bits to properly
-set up the hardware, eg for HBR passthrough.
-
-Add iec958 controls so the channel status bits can be passed in
-from userspace.
