This series proposes SW workarounds for Tegra194 HDA HW bugs. Following are the two issues seen:
- GCAP register does not reflect true capability. The actual number of SDO lines is "4", where as it reflects "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.
Sameer Pujar (3): 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
Through a quick glance, all changes look good.
Is the device already in market, i.e. it had hit users? If yes, I'm going to merge for 5.7, otherwise for 5.8.
thanks,
