Originally hda_bus takes its own ops (hda_bus_ops) to allow different
controller drivers giving individual implementations of PCM
attachment, etc.  But this never happened and we finally merged both
codec and controller helper codes.  Thus there is no merit to keep the
indirect accesses to functions via hda_bus_ops.

This patch replaces these calls with the direct local function calls
for simplification.

Move the small portion of the common sequence in hda_intel.c and
hda_tegra.c into hda_controller.c.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

... and replace with the existing hda-core helper codes.
This reduces lots of lines, finally.

Since struct hda_bus is now embedded into struct azx,
snd_hda_bus_new() is moved and expanded from hda_codec.c to
hda_controller.c, accordingly.  Also private_free bus ops and
private_data field are removed because we no longer need to point azx
object from bus (we can use container_of())

The spin locks are consolidated into the single one, bus->reg_lock.

One less redirection again.  This also requires the change of the call
order in the toplevel divers.  Namely, the bus has to be created at
first before other initializations since the memory allocation ops are
called through bus object now.

There is no much merit to keep the HD-audio codec and controller
helper codes in separate modules any longer.  Let's merge them into a
single helper module.

This patch just changes Makefile entries to merge two individual
modules to one.  The only code change is the removal of superfluous
MODULE_*() macros in one side.

Copied from the legacy driver code, no transition done yet.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

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.

Some HD-A codecs may add their own vendor 'set' verb to the regmap, thru func
snd_hdac_add_vendor_verb(). This patch sets the GET bit (bit 11)  when adding
the verb so that its peer vendor 'get' verb is actually added. This can avoid
I/O error when writing the 'set' verb thru remap, since HD-A regmap internally
looks up a writable vendor verb with GET bit set at first.

Merge tag 'asoc-v4.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Updates for v4.1

More updates for v4.1, pretty much all drivers:

 - Lots of cleanups from Lars, mainly moving things from the CODEC level
   to the card level.
 - Continuing improvements to rcar from Morimoto-san, pcm512x from
   Howard and Peter, the Intel platforms from Vinod, Jie, Jin and Han,
   and to rt5670 from Bard.
 - Support for some non-DSP Qualcomm platforms, Google's Storm
   platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC.

The Lenovo Thinkpad T450 requires the ALC292_FIXUP_TPT440_DOCK as well in
order to get working sound output on the docking stations headphone jack.

Patch tested on a Thinkpad T450 (20BVCTO1WW) using kernel 4.0-rc7 in
conjunction with a ThinkPad Ultradock.

Although some races in runtime PM refcount was fixed by the commit
[664c7155: ALSA: hda - Work around races of power up/down with
runtime PM], there is still a race in the following case:

CPU0:                   CPU1 :
runtime suspend:
  codec->in_pm = 1
                        snd_hdac_power_up_pm():
                          pm_runtime_get_sync() skipped
suspend finished:
  codec->in_pm = 0
                        snd_hdac_power_down_pm():
                          pm_runtime_put_*() is called!

For avoiding this situation, increment in_pm flag atomically when it's
non-zero, and decrement accordingly, to ensure that in_pm is set
consistently for the whole concurrent operations.

Also, since atomic_inc_not_zero() and atomic_dec_if_positive() are
lengthy inline functions, move snd_hdac_power_up_pm() and _down_pm()
to sound/hda/hdac_device.c as no inline functions.

The type field of HD-audio codec object should be exposed to

An element instance can have several elements with the same feature.
Some userspace applications can add such an element instance by add
operation with the number of elements. Then, the element instance
gets a memory object to keep states of these elements.

But the element instance has just one memory object for the elements.
This causes the same result to each read/write operations to the
different elements.

This commit fixes this bug by allocating enough memory objects to the
element instance for each of elements.
