This adds a driver for the HDA block in Tegra SoCs. The HDA bus is used to communicate with the HDMI codec on Tegra124.
Most of the code is re-used from the Intel/PCI HDA driver. It brings over only two of the module params, power_save and probe_mask.

When I run this on Jetson TK1 I get the following:
[ 1.571912] tegra-hda 70030000.hda: CORB reset timeout#1, CORBRP = 0
Is that expected?
The device seems to register properly:
$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: tegrahda [tegra-hda], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: TK1 [NVIDIA Tegra Jetson TK1], device 0: RT5640 PCM rt5640-aif1-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0
Would you mind sharing the procedure how you test this? I tried various incantations of this sort:
$ aplay -D hw:0,3 /usr/share/sounds/alsa/Noise.wav
or
$ aplay -D plughw:0,3 /usr/share/sounds/alsa/Noise.wav
to no avail.
