Subject[PATCH 0/3] Tegra194 HW Fixes
Date
This series proposes SW workarounds for Tegra194 HDA HW bugs.
Following are the two issues seen:
1. GCAP register does not reflect true capability.
The actual number of SDO lines is "4", where as it reflects "2".
2. With 4 SDO line configuration playback fails for,
44.1K/48K, 2-channel, 16-bps audio stream.

After fixing [1], issue [2] is uncovered.
As per recommendation by Tegra HW team the workarounds are pushed.

Testing done
============
* Verify GCAP register after registering HDA sound card
* Verify audio playback for 44.1K/48K, 2-channel, 16-bps.

ALSA: hda/tegra: correct number of SDO lines for Tegra194
ALSA: hda: add member to store ratio for stripe control
ALSA: hda/tegra: workaround playback failure on Tegra194
