ASoC: Add audio drivers for MSM 8952 targets 



Add snapshot for audio drivers for MSM targets. The code is
migrated from msm-3.10 kernel at the below commit -
ef68df2a5ef9f0e94a4425205bfd7f84406667c8
(Merge "Input: optimize events_per_packet count calculation")

Resolved ALSA core dependency of component based access for card
and checkpatch failiures for unnecessary out of memory print,
spell checks and blank line check after variable declarations.

wsa881x Audio CODEC



wsa881x Audio CODEC can support either I2C interface or Soundwire interface.

In Analog mode, this codec will operate as I2C slave device and

interacts with I2C controller for status, control and interrupt management.

The wsa881x device nodes will be represented as child nodes to I2C

master device node in the devicetree. Currently, the below devicetree

bindings are for I2C mode only and does not include soundwire mode.



Required properties:



 - compatible : "qcom,wsa881x-i2c-codec"

 - reg : Unique device ID of I2C slave device.



Optional properties:

- qcom,msm-gpios : Lists down all the gpio sets that are supported.

- qcom,pinctrl-names : Lists all the possible combinations of the gpio sets

mentioned in qcom,msm-gpios. Say we have 2^N combinations for N GPIOs, this

list all 2^N combinations.

- pinctrl-names : The combinations of gpio sets from above that are supported in

the flavor. This can be sometimes same as qcom, pinctrl-names i.e with 2^N

combinations or will have less incase if some combination is not supported.

- pinctrl-# : Pinctrl states as mentioned in pinctrl-names.



* wsa_intc



Required properties:



 - compatible :                            "qcom,wsa-irq"

 - interrupt-controller :                  Mark this device node as an

					   interrupt controller

 - #interrupt-cells :                      Should be 1

 - interrupt-parent :                      Parent interrupt controller

 - interrupts :                            Interrupt number on the parent

                                           interrupt controller

 - interrupt-names :                       Name of interrupt on the parent

                                           interrupt controller
