When HDMI NULL sample injection is enabled codec inserts null samples
into the audio FIFO for each Azalia frame in which it did not receive
any samples. This support is needed to prevent audio loss for HDMI
devices from some vendor(e.g. sony).

Device /dev/nvhdcpX is used to manage NVHDCP on framebuffer /dev/fbX.
These devices are created on hdmi driver initialition when it is
attached to dc. Currently only one nvhdcp device may be created. An ioctl
interface is in video/nvhdcp.h
Check for repeaters and store repeater info. userspace application
queries this status to authenticate the connection. When authentication
fails, auto-renegotiate every 1.75 seconds. Give up after 5 failed attempts,
reset after hotplug or policy change.
use TEGRA_DC_OUT_NVHDCP_POLICY_ON_DEMAND in tegra_dc_out.flags in board
panel configuration to select a different default policy at probe. Currently
only TEGRA_DC_OUT_NVHDCP_POLICY_ALWAYS_ON is supported.
