Takashi Iwai 78dd5e21b0 ALSA: hda - Add / fix kernel doc comments
Give some readable comment in kernel doc style for each exported
function, as I promised in the previous meetings.  While we're at it,
fix the wrong comments, too.

Takashi Iwai 1475241272 ALSA: hda - Add the controller helper codes to hda-core module
This patch adds the controller helper codes to hda-core library.
The I/O access ops are added to the bus ops.  The CORB/RIRB, the basic
attributes like irq# and iomap address, some locks and the list of
streams are added to the bus object, together with the stream object
and its helpers.

Currently the codes are just copied from the legacy driver, so you can
find duplicated codes in both directories.  Only constants are removed
from the original hda_controller.h.  More integration work will follow
in the later patches.

Takashi Iwai e311782acd ALSA: hda - Re-add tracepoints to HD-audio core driver
Now let's take the basic tracepoints back to the HD-audio driver.
The three bus tracepoints, hda_send_cmd, hda_get_response and
hda_unsol_event are revived but in a slightly different form.
Since we don't assign the card number there, print the bus device name
instead.

Takashi Iwai d068ebc25e ALSA: hda - Move some codes up to hdac_bus struct
A few basic codes for communicating over HD-audio bus are moved to
struct hdac_bus now.  It has only command and get_response ops in
addition to the unsolicited event handling.

Note that the codec-side tracing support is disabled temporarily
during this transition due to the code shuffling.  It will be
re-enabled later once when all pieces are settled down.
