Takashi Iwai 19260818a9 ALSA: ac97: Treat snd_ac97_bus_ops as const
This is a preliminary patch to allow const for snd_ac97_bus_ops
definitions in each driver's code.  The ops reference is read-only,
hence it can be declared as const for further optimization.

There should be no functional changes by this patch.

Takashi Iwai 08ceab9d87 ASoC: Updates for v4.3
Not many updates to the core here, but an awful lot of driver updates
 this time round:
 
  - Factoring out of AC'97 reset code into the core
  - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
    RT298 and ST STI controllers.
  - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
    RT5650.
  - Initial driver support for Intel Skylake devices.
  - A large number of cleanups for Lars-Peter Clausen and Axel Lin.

Lars-Peter Clausen 9bc07dfbcd ALSA: ac97: Switch to dev_pm_ops
Convert the ac97_bus from legacy suspend/resume callbacks to dev_pm_ops.

Since there isn't anything special to do at the bus level the bus driver
does not have to implement any callbacks. The device driver core will
automatically pick up and execute the device's PM ops.

As there is only a single AC'97 driver implementing suspend and resume,
update both the core and driver at the same time to avoid unnecessary code
churn.

While we are at it also drop the ifdefs around the suspend/resume functions
to increase compile test coverage.

Lars-Peter Clausen 5f1d980ee9 ALSA: ac97: Add helper function to reset the AC97 device
There is currently a lot of code duplication in ASoC drivers regarding the
reset handling of devices. This patch introduces a new generic reset
function in the generic AC'97 framework that can be used to replace most
the custom reset functions.

Nicolas Pitre e1036502e5 [PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystem
Commit 2d4ba4a3b9 introduced a dependency
that was never meant to exist when the ac97_bus.c module was created.
Move ac97_bus.c up the directory hierarchy to make sure it is built when
selected even if sound is configured out so things work as originally
intended.
