Locking in nvhdcp was set up in such a way that we couldn't
change the state of the HDMI plug while negotiating the HDCP connection.
Another lock was added that is only taken when the state of the plug or
hdcp session are changed. This enables correct failure if the plug is removed
during negotiation.

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.
