sound updates for 4.8

Browse Source 
Majority of this update is about ASoC, including a few new drivers,
 and the rest are mostly minor changes.  The only substantial change in
 ALSA core is about the additional error handling in the
 compress-offload API.  Below are highlights:
 
 - Add the error propagating support in compress-offload API
 
 - HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
   default mixer setup change ot turn off the loopback
 
 - Lots of updates for ASoC Intel drivers, mostly board support and bug
   fixing, and to the NAU8825 driver
 
 - Work on generalizing bits of simple-card to allow more code sharing
   with the Renesas rsrc-card (which can't use simple-card due to DPCM)
 
 - Removal of the Odroid X2 driver due to replacement with simple-card
 
 - Support for several new Mediatek platforms and associated boards
 
 - New ASoC drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom
   Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504,
   Realtek RT5514 and Wolfson WM8758

CS35L33 Speaker Amplifier
Required properties:
- compatible : "cirrus,cs35l33"
- reg : the I2C address of the device for I2C
- VA-supply, VP-supply : power supplies for the device,
as covered in
Documentation/devicetree/bindings/regulator/regulator.txt.
Optional properties:
- reset-gpios : gpio used to reset the amplifier
- interrupt-parent : Specifies the phandle of the interrupt controller to
which the IRQs from CS35L33 are delivered to.
- interrupts : IRQ line info CS35L33.
(See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
for further information relating to interrupt properties)
- cirrus,boost-ctl : Booster voltage use to supply the amp. If the value is
0, then VBST = VP. If greater than 0, the boost voltage will be 3300mV with
a value of 1 and will increase at a step size of 100mV until a maximum of
8000mV.
- cirrus,ramp-rate : On power up, it affects the time from when the power
up sequence begins to the time the audio reaches a full-scale output.
On power down, it affects the time from when the power-down sequence
begins to when the amplifier disables the PWM outputs. If this property
is not set then soft ramping will be disabled and ramp time would be
20ms. If this property is set to 0,1,2,3 then ramp times would be 40ms,
60ms,100ms,175ms respectively for 48KHz sample rate.
- cirrus,boost-ipk : The maximum current allowed for the boost converter.
The range starts at 1850000uA and goes to a maximum of 3600000uA
with a step size of 15625uA. The default is 2500000uA.
- cirrus,imon-adc-scale : Configures the scaling of data bits from the IMON
ADC data word. This property can be set as a value of 0 for bits 15 down
to 0, 6 for 21 down to 6, 7, for 22 down to 7, 8 for 23 down to 8.
Optional H/G Algorithm sub-node:
The cs35l33 node can have a single "cirrus,hg-algo" sub-node that will enable
the internal H/G Algorithm.
- cirrus,hg-algo : Sub-node for internal Class H/G algorithm that
controls the amplifier supplies.
Optional properties for the "cirrus,hg-algo" sub-node:
- cirrus,mem-depth : Memory depth for the Class H/G algorithm measured in
LRCLK cycles. If this property is set to 0, 1, 2, or 3 then the memory
depths will be 1, 4, 8, 16 LRCLK cycles. The default is 16 LRCLK cycles.
cirrus,release-rate : The number of consecutive LRCLK periods before
allowing release condition tracking updates. The number of LRCLK periods
start at 3 to a maximum of 255.
- cirrus,ldo-thld : Configures the signal threshold at which the PWM output
stage enters LDO operation. Starts as a default value of 50mV for a value
of 1 and increases with a step size of 50mV to a maximum of 750mV (value of
0xF).
- cirrus,ldo-path-disable : This is a boolean property. If present, the H/G
algorithm uses the max detection path. If not present, the LDO
detection path is used.
- cirrus,ldo-entry-delay : The LDO entry delay in milliseconds before the H/G
algorithm switches to the LDO voltage. This property can be set to values
from 0 to 7 for delays of 5ms, 10ms, 50ms, 100ms, 200ms, 500ms, 1000ms.
The default is 100ms.
- cirrus,vp-hg-auto : This is a boolean property. When set, class H/G VPhg
automatic updating is enabled.
- cirrus,vp-hg : Class H/G algorithm VPhg. Controls the H/G algorithm's
reference to the VP voltage for when to start generating a boosted VBST.
The reference voltage starts at 3000mV with a value of 0x3 and is increased
by 100mV per step to a maximum of 5500mV.
- cirrus,vp-hg-rate : The rate (number of LRCLK periods) at which the VPhg is
allowed to increase to a higher voltage when using VPhg automatic
tracking. This property can be set to values from 0 to 3 with rates of 128
periods, 2048 periods, 32768 periods, and 524288 periods.
The default is 32768 periods.
- cirrus,vp-hg-va : VA calculation reference for automatic VPhg tracking
using VPMON. This property can be set to values from 0 to 6 starting at
1800mV with a step size of 50mV up to a maximum value of 1750mV.
Default is 1800mV.

cs35l33: cs35l33@40 {
compatible = "cirrus,cs35l33";

- cirrus,use-sdout2 : This is a boolean property. If present, it indicates
the hardware design connects both SDOUT1 and SDOUT2
pins to output data. Otherwise, it indicates that
only SDOUT1 is connected for data output.
* CS53l30 supports 4-channel data output in the same
* frame using two different ways:
* 1) Normal I2S mode on two data pins -- each SDOUT
* carries 2-channel data in the same time.
* 2) TDM mode on one signle data pin -- SDOUT1 carries
