sound updates for 4.6-rc1

After a heavy storm by syzkaller in 4.5 cycle, we have relatively few
 changes in the core at this time while a lot of changes are found in
 the driver side, unsurprisingly.  Below are some highlights:
 
 ALSA core:
 - A few more hardening in ALSA timer codes
 - An extension of sequencer API for advertising the card / pid
 - Small fixes in compress-offload and jack layers
 
 HD-audio:
 - Dynamic PCM assignment in HDMI/DP codec; preparation for upcoming
   DP-MST support
 - Lots of code refactoring for sharing with ASoC SKL driver
 - Regression fixes for Intel HDMI/DP
 - Fixups for CX20724 codec, Lenovo AiO
 
 USB-audio:
 - Add quirk_alias option to make quirk debugging easier
 - Fixes for possible Oops by malformed firmware
 
 Firewire:
 - Add support for FW-1804 in tascam driver
 - Improvements / changes in card registration, multi stream handling,
   etc for DICE
 - Lots of code refactoring
 
 ASoC:
 - Enhancements of still ongoing topology API
 - Lots of commits for Intel Skylake support including HDMI support
 - A few Intel Atom driver updates for recent devices
 - Lots of improvements to the Renesas drivers
 - Capture support for Qualcomm drivers
 - Support for TI DaVinci DRA7xxx devices
 - New machine drivers for Freescale systems with Cirrus CODECs,
   Mediatek systems with RT5650 CODECs
 - New CPU drivers for Allwinner S/PDIF controllers
 - New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514

+
+There is no DT settings for SSIU, because SSIU will be automatically

+SSIU can avoid some under/over run error, because it has some buffer.
+But you can't use it if SSI was PIO mode.
+In DMA mode, you can select not to use SSIU by using "no-busif" on DT.

+=============================================

+=============================================

+
+You can use PIO mode which is for connection check by using.
+Note: The system will drop non-SSI modules in PIO mode
+even though if DT is selecting other modules.
+
+	&ssi0 {

+** DMA mode without SSIU
+
+You can use DMA without SSIU.
+Note: under/over run, or noise are likely to occur
+
+	&ssi0 {
+		no-busif;

+
+** PIN sharing
+
+Each SSI can share WS pin. It is based on platform.

+To support DP MST audio, HD Audio hdmi codec driver introduces virtual pin
+and dynamic pcm assignment.
+
+Virtual pin is an extension of per_pin. The most difference of DP MST
+from legacy is that DP MST introduces device entry. Each pin can contain
+several device entries. Each device entry behaves as a pin.
+
+As each pin may contain several device entries and each codec may contain
+several pins, if we use one pcm per per_pin, there will be many PCMs.
+The new solution is to create a few PCMs and to dynamically bind pcm to
+per_pin. Driver uses spec->dyn_pcm_assign flag to indicate whether to use
+the new solution.
+
+PCM
+===
+To be added
+
+
+Jack
+====
+
+Presume:
+ - MST must be dyn_pcm_assign, and it is acomp (for Intel scenario);
+ - NON-MST may or may not be dyn_pcm_assign, it can be acomp or !acomp;
+
+So there are the following scenarios:
+ a. MST (&& dyn_pcm_assign && acomp)
+ b. NON-MST && dyn_pcm_assign && acomp
+ c. NON-MST && !dyn_pcm_assign && !acomp
+
+Below discussion will ignore MST and NON-MST difference as it doesn't
+impact on jack handling too much.
+
+Driver uses struct hdmi_pcm pcm[] array in hdmi_spec and snd_jack is
+a member of hdmi_pcm. Each pin has one struct hdmi_pcm * pcm pointer.
+
+For !dyn_pcm_assign, per_pin->pcm will assigned to spec->pcm[n] statically.
+
+For dyn_pcm_assign, per_pin->pcm will assigned to spec->pcm[n]
+when monitor is hotplugged.
+
+
+Build Jack
+----------
+
+- dyn_pcm_assign
+Will not use hda_jack but use snd_jack in spec->pcm_rec[pcm_idx].jack directly.
+
+- !dyn_pcm_assign
+Use hda_jack and assign spec->pcm_rec[pcm_idx].jack = jack->jack statically.
+
+
+Unsolicited Event Enabling
+--------------------------
+Enable unsolicited event if !acomp.
+
+
+Monitor Hotplug Event Handling
+------------------------------
+- acomp
+pin_eld_notify() -> check_presence_and_report() -> hdmi_present_sense() ->
+sync_eld_via_acomp().
+Use directly snd_jack_report() on spec->pcm_rec[pcm_idx].jack for
+both dyn_pcm_assign and !dyn_pcm_assign
+
+- !acomp
+Hdmi_unsol_event() -> hdmi_intrinsic_event() -> check_presence_and_report() ->
+hdmi_present_sense() -> hdmi_prepsent_sense_via_verbs()
+Use directly snd_jack_report() on spec->pcm_rec[pcm_idx].jack for dyn_pcm_assign.
+Use hda_jack mechanism to handle jack events.
+
+
+Others to be added later
