Currently, our implementation of drm_connector_funcs.detect is
based on getting a valid EDID.
This requirement makes the driver fail to detect connected
connectors in case of EDID corruption, which prevents from falling
back to modes provided by builtin or user-provided EDIDs.

Add HDMI audio support. Adds mcasp0_pins, clk_mcasp0_fixed,

Register ASoC HDMI codec for audio functionality and adds device tree
binding for audio configuration.
With the registered HDMI codec the tda998x node can be used like a

Define struct tda998x_audio_params in include/drm/i2c/tda998x.h and

Beware that while the kernel side of this might be relatively easy to

Update the UAPI header to the latest version in the Linux kernel. This
changes the struct drm_tegra_gem_mmap to properly handle offsets on 64-

See commit bdf765071a8b ("drm/tegra: gem: Return 64-bit offset for
mmap(2)") in the Linux kernel (as of v4.1).
