dt-bindings: platform: msm: Add DT bindings for GENI serial engine driver 



Add DT bindings for GENI serial engine driver which provides
common functionality used by other serial bus drivers
such as I2c, SPI, UART), and does resource management for
those drivers.

Qualcomm Technologies, Inc. GENI Serial Engine Driver



GENI Serial Engine Driver is used to configure and read the configuration

from the Serial Engines on Qualcomm Technologies, Inc. Universal Peripheral

(QUPv3) core. It is also used to enable the stage1 IOMMU translation and

manage resources associated with the QUPv3 core.



Required properties:

- compatible:		Must be "qcom,qupv3-geni-se".

- reg:			Must contain QUPv3 register address and length.

- qcom,bus-mas-id:	Master Endpoint ID for bus driver.

- qcom,bus-slv-id:	Slave Endpoint ID for bus driver.



Optional properties:

- qcom,iommu-s1-bypass:	Boolean flag to bypass IOMMU stage 1 translation.



Optional subnodes:

qcom,iommu_qupv3_geni_se_cb:	Child node representing the QUPV3 context

				bank.



Subnode Required properties:

- compatible :		Must be "qcom,qupv3-geni-se-cb";

- iommus:		A list of phandle and IOMMU specifier pairs that

			describe the IOMMU master interfaces of the device.



Example:

	qupv3_0: qcom,qupv3_0_geni_se@8c0000 {

		compatible = "qcom,qupv3-geni-se";

		reg = <0x8c0000 0x6000>;

		qcom,bus-mas-id = <100>;

		qcom,bus-slv-id = <300>;



		iommu_qupv3_0_geni_se_cb: qcom,iommu_qupv3_0_geni_se_cb {

			compatible = "qcom,qupv3-geni-se-cb";

			iommus = <&apps_smmu 0x1 0x0>;

		};

	}
