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.
