最近整理的一些msm8909平台英文文档2 - how

For example, if the project you compiled is isinstru, Mod kernel/arch/arm/boot/dts/qcom/isinstru.dtsi, add the context below. &usb_otg { qcom,hsusb-otg-mode = <3>; interrupts = <0 134 0>,<0 140 0>,<0 136 0>; interrupt-names = "core_irq", "async_irq", "phy_irq"; simotg,vbus_use_ldo; simotg,vbus_ldo_en_pin = <&msm_gpio 112 0>; };

In this case, we use a "gpio 112" to control the switch of otg power, you must config it according to your hardware.
