我现在要实现VBUS唤醒系统，（即系统休眠后插入
usb可以实现唤醒系统，并且有adb口，目前是休眠之后插入
usb无法唤醒）
目前抓到的唤醒log如下：
[ 282.641013] PM: pm_system_irq_wakeup: 175 triggered c263000.thermal-sensor
[ 282.641764] PM: PM: Pending Wakeup Sources: [timerfd]
[ 282.669925]
usb_extcon_detect_cable : id = 1, vbus = 0
[ 282.709202] [drm] [msm-dsi-warn]: secondary default panel not found
我的预期是id = 1, vbus = 1
这是log打印相关的代码：
static void
usb_extcon_detect_cable(struct work_struct *work)
{
int id, vbus;
struct
usb_extcon_info *info = container_of(to_delayed_work(work),
struct
usb_extcon_info,
wq_detcable);
/* check ID and VBUS and update cable state */
id = info->id_gpiod ?
gpiod_get_value_cansleep(info->id_gpiod) : 1;
vbus = info->vbus_gpiod ?
gpiod_get_value_cansleep(info->vbus_gpiod) : id;
printk("ct %s : id = %d, vbus = %d\n", __func__, id, vbus);
/* at first we clean states which are no longer
active */
if (id) {
if (info->vbus_out_gpiod)
gpiod_set_value_cansleep(info->vbus_out_gpiod, 0);
extcon_set_state_
sync(info->edev, EXTCON_
USB_HOST, false);
}
if (!vbus)
extcon_set_state_
sync(info->edev, EXTCON_
USB, false);
if (!id) {
if (info->vbus_out_gpiod)
gpiod_set_value_cansleep(info->vbus_out_gpiod, 1);
extcon_set_state_
sync(info->edev, EXTCON_
USB_HOST, true);
} else {
if (vbus)
extcon_set_state_
sync(info->edev, EXTCON_
USB, true);
}
}
这是我在devicetree/qcom/neo-pmic-overlay.dtsi的配置：你检查下哪些地方可能配置的不对：

};补充一下，gpio5注册的中断号是cat /proc/interrupts | grep spmi

usb0我 cat /proc/interrupts | grep spmi
304: 0 0 0 0 spmi-gpio 4 Edge soc:extcon_
usb0
而代码里interrupt-parent = <&spmi_bus>;这两者需要对应吗
本文详细介绍了WinCE系统中USBFunction的三种工作模式：SERIAL、RNDIS及MASS_STORAGE，并针对每种模式提供了具体的配置示例，包括解决ActiveSync冲突问题的方法。
