Since the recent rewrite of HD-audio infrastructure,
CONFIG_SND_HDA_RECONFIG has a slightly different meaning. In the
earlier versions, it implicitly assumed only the usage via hwdep sysfs
entries. Meanwhile, in the recent version, this option is meant to
enable the reconfig code in HD-audio driver, which may be used by the
patch loader without hwdep interface.
This patch tries to clarify the usage pattern a bit better, hopefully
avoid the further confusion.

Since the recent integration of kctl jack and input jack layers, we
can basically build the jack layer even without input devices. That
is, the jack layer itself can be built with conditional to enable the
input device support or not, while the users may enable always
CONFIG_SND_JACK unconditionally.
For achieving it, this patch changes the following:
- A new Kconfig, CONFIG_SND_JACK_INPUT_DEV, was introduced to indicate
whether the jack layer supports the input device,
- A few items in snd_jack struct and relevant codes are conditionally
built upon CONFIG_SND_JACK_INPUT_DEV,
- The users of CONFIG_SND_JACK drop the messy dependency on
CONFIG_INPUT.
This change also automagically fixes a potential bug in HD-audio
driver Arnd reported, where the NULL or uninitialized jack instance is
dereferenced.

The file is moved to hda core and renamed to hdac_i915.c, so can be used
by both legacy HDA driver and new Skylake audio driver.
- Add snd_hdac_ prefix to the public APIs.
- The i915 audio component is moved to core bus and dynamically allocated.
- A static pointer hdac_acomp is used to help bind/unbind callbacks to get
this component, because the sound card's private_data is used by the azx
chip pointer, which is a legacy structure. It could be removed if private
_data changes to some core structure which can be extended to find the
bus.
- snd_hdac_get_display_clk() is added to get the display core clock for
HSW/BDW.
- haswell_set_bclk() is moved to hda_intel.c because it needs to write the
controller registers EM4/EM5, and only legacy HD-A needs it for HSW/BDW.
- Move definition of HSW/BDW-specific registers EM4/EM5 to hda_register.h
and rename them to HSW_EM4/HSW_EM5, because other HD-A controllers have
different layout for the extended mode registers.

Currently the ALSA jack core registers only input devices for each jack
registered. These jack input devices are not readable by userspace devices
that run as non root. This patch series will implement kctls inside the
core jack part, including kctls creating, status changing report, for both
HD-Audio and ASoC jack. This allows non root userspace to read jack status
and act on it.
This patch adds a new API called snd_jack_add_new_kctl(), which will create
a kcontrol, add it to the card, and also attach it to the jack kctl list.
This patch also initialises the jack kctl list after jack is newed, and
reports kctl status when jack insertion/removal events occur.
snd_jack_new() is updated in the following patches to also support creating
phantom jacks and jack kcontrols. We then remove these duplicated features
from HDA jack and have jack kctls handled by core throughout HDA and ASoC.

The commit commit [33f4acd3b2: ALSA: hda - Enable mic mute hotkey

involving with the input event handling. Although the relevant code
is protected via IS_ENABLED(CONFIG_INPUT), this doesn't suffice when
the audio driver is built in while the input is module.
As an easy workaround, this patch forcibly selects CONFIG_INPUT in
Kconfig. This shouldn't be a practical problem since CONFIG_INPUT is
almost mandatory for all systems. Also, this allows to remove the
ugly ifdefs in the code.

When a Kconfig of a codec driver doesn't match with the controller
(CONFIG_SND_HDA_INTEL), it'll result in the non-working automatic

So far, CONFIG_SND_HDA_CODEC_* kconfigs have been booleans due to
historical reasons. The major reason was that the automatic codec
driver probing wouldn't work if user sets a codec driver as a module
while the controller driver as a built-in. And, another reason was to
avoid exporting symbols of the helper codes when all drivers are built
in.
But, this sort of "kindness" rather confuses people in the end,
especially makes the config refinement via localmodconfig unhappy.
Also, a codec module would still work if you re-bind the controller
driver via sysfs (although it's no automatic loading), so there might
be a slight use case.
That said, better to let people fallen into a pitfall than being too
smart and restrict something. Let's make things straightforward: now
all CONFIG_SND_HDA_CODEC_* become tristate, and all symbols exported
unconditionally.

There are some snd changes for the HDMI audio interactions on haswell,

Major changes:
AMD finally released the dynamic power management code for all their

also a huge amount of code, in fact it is most of this pull request.
Since it landed there has been a lot of community testing and Alex has

now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable
dynamic powermanagement for anyone.
New drivers:
Renesas r-car display unit.

- core: GEM CMA prime support, use new w/w mutexs for TTM
reservations, cursor hotspot, doc updates
- dvo chips: chrontel 7010B support
- i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
support (this time for sure)
- nouveau: async buffer object deletion, context/register init
updates, kernel vp2 engine support, GF117 support, GK110 accel
support (with external nvidia ucode), context cleanups.
- exynos: memory leak fixes, Add S3C64XX SoC series support, device

- mgag200: hw cursor support, g200 mode limiting

For Intel Haswell chip, HDA controller and codec have
power well dependency from GPU side. This patch added support
to request/release power well in audio driver. Power save
feature should be enabled to get runtime power saving.
There's deadlock when request_module(i915) in azx_probe.
It looks like:
device_lock(audio pci device) -> azx_probe -> module_request
(or symbol_request) -> modprobe (userspace) -> i915 init ->
drm_pci_init -> pci_register_driver -> bus_add_driver -> driver_attach ->
which in turn tries all locks on pci bus, and when it tries the one on the
audio device, it will deadlock.
This patch introduce a work to store remaining probe stuff, and let
request_module run in safe work context.
