QCN SDIO bridge driver

======================



The Q6-WCSS runs few services that need to be interfaced on the host device. The

QCN SDIO bridge driver provides the interfacing between the function-1 driver

and the services running on the host device, ther by maintaining a streamlined

communication between Q6-WCSS and host device.



Example Services: Diag, IPC router, QMI



QCN SDIO Bridge Node:

=====================

A QCN SDIO bridge driver node is used to represent the client driver instance.

It is needed as a child node to SOC parent node through which

it is accessible to host.



Required properties:

--------------------

- compatible		Should be one of

				"qcom,sdio-bridge" for MSM8996 SOCs



- qcom,client-id	Client ID, Should be on of

				1: TTY, 2: WLAN, 3: QMI, 4: DIAG;



- qcom,client-name	Client Name, Should be one of

			"SDIO_AL_CLIENT_TTY", "SDIO_AL_CLIENT_WLAN"

			"SDIO_AL_CLIENT_QMI", "SDIO_AL_CLIENT_DIAG"



- qcom,ch-name		"SDIO_AL_TTY_CH0", "SDIO_AL_WLAN_CH0",

			"SDIO_AL_WLAN_CH1", "SDIO_AL_QMI_CH0",



Example:

--------

/* MSM8996 */

soc {

	sdio_bridge_tty: qcom,sdio-bridge@0 {

		 compatible = "qcom,sdio-bridge";

		 qcom,client-id = <1>;

		 qcom,client-name = "SDIO_AL_CLIENT_TTY";

		 qcom,ch-name = "SDIO_AL_TTY_CH0";

		 status = "disabled";

	};



	sdio_bridge_ipc: qcom,sdio-bridge@1 {

		 compatible = "qcom,sdio-bridge";

		 qcom,client-id = <3>;

		 qcom,client-name = "SDIO_AL_CLIENT_QMI";

		 qcom,ch-name = "SDIO_AL_QMI_CH0";

		 status = "disabled";

	};



	sdio_bridge_diag: qcom,sdio-bridge@3 {

		  compatible = "qcom,sdio-bridge";

		  qcom,client-id = <4>;

		  qcom,client-name = "SDIO_AL_CLIENT_DIAG";

		  qcom,ch-name = "SDIO_AL_DIAG_CH0";

		  status = "disabled";

	};

};
