soc: qcom: Add snapshot of BAM DMUX driver

Qualcomm BAM Data Multiplexer Driver

Required properties:

- compatible : should be "qcom,bam_dmux"

- reg : the location and size of the BAM hardware

- interrupts : the BAM hardware to apps processor interrupt line

Optional properties:

-qcom,satellite-mode: the hardware needs to be configured in satellite mode

-qcom,rx-ring-size: the size of the receive ring buffer pool, default is 32

-qcom,max-rx-mtu: the maximum receive MTU that can be negotiated, in bytes.

	Default is 2048.  Other possible values are 4096, 8192, and 16384.

-qcom,no-cpu-affinity: boolean value indicating that workqueue CPU affinity

	is not required.

Example:

	qcom,bam_dmux@fc834000 {

		compatible = "qcom,bam_dmux";

		reg = <0xfc834000 0x7000>;

		interrupts = <0 29 1>;

		qcom,satellite-mode;

		qcom,rx-ring-size = <64>;

		qcom,max-rx-mtu = <8192>;

		qcom,no-cpu-affinity;

	};

	  system load and state. It also supports limiting min and

	  max online CPUs from userspace.

	  Support Muxed Data Channels over BAM interface.

	  BAM has a limited number of pipes.  This driver

	  provides a means to support more logical channels

	  via muxing than BAM could without muxing.
