Subject: [PATCH 0/5] ALSA: hda/ca0132 - Fix no-audio issues and add documentation.

This patch series attempts to fix the no audio at startup issues that
have been occurring for some users, using information gained through
reverse engineering the ca0132's onboard 8051 processor.

The issue of no audio on startup seemed to be caused by two separate
problems: not resetting the codec upon initialization, and not making
sure the DSP allocates it's DMA channels correctly.

Tested and working on all cards, except for the AE-7. The AE-7 shouldn't
have any issues, however, I don't have one on hand to test.

As an aside, I'm not sure how to classify which commits this necessarily
'fixes', as it's covering multiple areas. Please let me know if this is
necessary.

Connor McAdams (5):
  ALSA: hda/ca0132 - Reset codec upon initialization.
  ALSA: hda/ca0132 - Add stream port remapping function.
  ALSA: hda/ca0132 - Add 8051 exram helper functions.
  ALSA: hda/ca0132 - Ensure DSP is properly setup post-firmware
    download.
  ALSA: hda/ca0132 - Remove now unnecessary DSP setup functions.
