Merge "phy: msm: ssusb: Power down SSPHY to avoid leakage in probe()"

- qcom,vbus-valid-override: If present, indicates VBUS pin is not connected to

the USB PHY and the controller must rely on external VBUS notification in

order to manually relay the notification to the SSPHY.

-qcom,keep-powerdown: If present, power down the SSPHY to avoid leakage current.

Example:

ssphy@f9200000 {

	if (of_property_read_bool(dev->of_node, "qcom,vbus-valid-override"))

		phy->phy.flags |= PHY_VBUS_VALID_OVERRIDE;

	/* Power down PHY to avoid leakage at 1.8V LDO */

	if (of_property_read_bool(dev->of_node, "qcom,keep-powerdown")) {

		msm_ssusb_ldo_enable(phy, 1);

		msm_ssusb_enable_clocks(phy);

		msm_usb_write_readback(phy->base, SS_PHY_CTRL4,

					TEST_POWERDOWN, TEST_POWERDOWN);

		msm_ssusb_disable_clocks(phy);

		msm_ssusb_ldo_enable(phy, 0);

		msm_ssusb_config_vdd(phy, 0);

	}

	phy->phy.init			= msm_ssphy_init;

	phy->phy.set_suspend		= msm_ssphy_set_suspend;
