BG-Daemon : When Modem goes down, to re-establish the connections,

BG-Daemon toggles the bg-reset gpio to reset BG.



Required properties:

- compatible : should be "qcom,bg-daemon"

- qcom,bg-reset-gpio : gpio for the apps processor use to soft reset BG

- ssr-reg1-supply : Power supply needed to power up the BG device.

                When BG brought up this regulator will be in normal power mode.

- ssr-reg2-supply : Power supply needed to power up the BG device.

                When BG BG brought up this regulator will be in normal power mode.



Example:

	qcom,bg-daemon {

		compatible = "qcom,bg-daemon";

		qcom,bg-reset-gpio = <&pm660_gpios 5 0>;

		ssr-reg1-supply = <&pm660_l3>;

		ssr-reg2-supply = <&pm660_l9>;

Qualcomm technologies Inc bg-spi



BG-COM SPI : bg-spi is used for the  communication with Blackghost

chipset. It uses SPI protocol for communication.

BG-COM: bgcome is a thin transport layer over glink which provides

the read/write APIs to communicate with Blackghost chipset.



Required properties:

- compatible : should be "qcom,bg-spi"

- spi-max-frequency : Maximum SPI clocking speed of device in Hz

- qcom,irq-gpio : GPIO pin

- reg : Register set



Example:

	spi@78b6000 { /* BLSP1 QUP2 */

		status = "ok";

		qcom,bg-spi {

			compatible = "qcom,bg-spi";

			reg = <0>;

			spi-max-frequency = <19200000>;

			interrupt-parent = <&msm_gpio>;

			qcom,irq-gpio = <&msm_gpio 110 1>;

		};
