sound updates for 4.7-rc1

Browse Source 
This time was again a relatively calm development cycle; most of
 updates are about drivers, and no radical changes are seen in any
 core code.  Here are some highlights:
 
 ALSA core:
 - Continued hardening of ALSA hrtimer
 - A few leak fixes in timer interface
 - Fix poll error handling in PCM and compress
 - Add error propagation in compress API
 - Removal of dead rtctimer driver
 
 HD-audio:
 - Native ELD notify support for i915 HDMI
 - Realtek ALC234 & co support
 - Code refactoring to standardize chmap support
 - Continued development for SKL HDMI core support
 
 Firewire:
 - Apply delayed card registration to all drivers
 - Improved / stabilized the handling of PCM stream start / stop
 - Add tracepoints to dump a part of isochronous packet data
 - Fixed incoming/outgoing packet parameter usages
 - Add support for M-Audio profire series
 
 USB-audio:
 - Fixes for UAC2 clock source
 - SS+ support
 - Workaround for oft-seen repeated sample rate read errors
 
 ASoC:
 - Further slow progress on the topology code
 - Substantial updates and improvements for the da7219, es8328,
   fsl-ssi, Intel and rcar drivers.
 - Compress error handling in WM ADSP driver

Texas Instruments DaVinci McBSP module
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This binding describes the "Multi-channel Buffered Serial Port" (McBSP)
audio interface found in some TI DaVinci processors like the OMAP-L138 or AM180x.
Required properties:
~~~~~~~~~~~~~~~~~~~~
- compatible :
"ti,da850-mcbsp" : for DA850, AM180x and OPAM-L138 platforms
- reg : physical base address and length of the controller memory mapped
region(s).
- reg-names : Should contain:
* "mpu" for the main registers (required).
* "dat" for the data FIFO (optional).
- dmas: three element list of DMA controller phandles, DMA request line and
TC channel ordered triplets.
- dma-names: identifier string for each DMA request line in the dmas property.
These strings correspond 1:1 with the ordered pairs in dmas. The dma
identifiers must be "rx" and "tx".
Optional properties:
~~~~~~~~~~~~~~~~~~~~
- interrupts : Interrupt numbers for McBSP
- interrupt-names : Known interrupt names are "rx" and "tx"
- pinctrl-0: Should specify pin control group used for this controller.
- pinctrl-names: Should contain only one value - "default", for more details
please refer to pinctrl-bindings.txt
Example (AM1808):
~~~~~~~~~~~~~~~~~
mcbsp0: mcbsp@1d10000 {
compatible = "ti,da850-mcbsp";
pinctrl-names = "default";
pinctrl-0 = <&mcbsp0_pins>;
reg = <0x00110000 0x1000>,
<0x00310000 0x1000>;
reg-names = "mpu", "dat";
interrupts = <97 98>;
interrupts-names = "rx", "tx";
dmas = <&edma0 3 1
&edma0 2 1>;
dma-names = "tx", "rx";
status = "okay";

Say Y here to enable RTC timer support for ALSA. ALSA uses
the RTC timer as a precise timing source and maps the RTC
timer to ALSA's timer interface. The ALSA sequencer code also
can use this timing source.
To compile this driver as a module, choose M here: the module
will be called snd-rtctimer.
Note that this option is exclusive with the new RTC drivers
(CONFIG_RTC_CLASS) since this requires the old API.
config SND_SEQ_RTCTIMER_DEFAULT
bool "Use RTC as default sequencer timer"
depends on SND_RTCTIMER && SND_SEQUENCER
depends on !SND_SEQ_HRTIMER_DEFAULT
default y
help
Say Y here to use the RTC timer as the default sequencer
timer. This is strongly recommended because it ensures
precise MIDI timing even when the system timer runs at less
than 1000 Hz.
If in doubt, say Y.
config SND_DYNAMIC_MINORS
