9x07-usb state拔出usb线后状态仍为CONFIGURED，影响休眠（已解决）

问题描述：拔出usb线后usb没有进入lpm模式，导致系统无法休眠

/ # cat /proc/cmdline

cat /proc/cmdline

noinitrd ro console=NULL androidboot.hardware=qcom ehci-hcd.park=3 msm_rtb.filter=0x37 lpm_levels.sleep_disabled=1 early

con=msm_hsl_uart,0x78b1000 androidboot.serialno=3b9980 androidboot.authorized_kernel=true androidboot.baseband=msm rootf

stype=ubifs rootflags=bulk_read root=ubi0:rootfs ubi.mtd=14 custapp=/dev/ubi2_0

此时执行休眠提示

sh: write error: Device or resource busy

************************************************************

去掉lpm_levels.sleep_disabled=1后，设置 # echo off > /sys/power/autosleep （或者去掉CONFIG_PM_AUTOSLEEP）

执行休眠结果

/sys/devices/virtual/android_usb/android0 # echo mem > /sys/power/state

可以使用这个指令打印usb状态机的log：echo file phy-msm-usb.c +p > /sys/kernel/debug/dynamic_debug/control

考虑LPM对usb的控制，特别是vbus部分，由于没有采用smb芯片，应配置成pmic引脚监测vbus的方式

参考文档 MDM9x07\BSP\PMIC\80_NH740_69_VBUS_DETECTION_USING_PMIC.pdf

主要有3点修改：

1. deconfig文件增加CONFIG_GPIO_USB_DETECT=y

2. dts增加pmic的mpp引脚监测

/* MPP pin 2 config for VBUS_DETECT interrupt line */

&pm8019_mpps {

mpp@a100 {

qcom,mode = <0>; /* Digital input */

qcom,vin-sel = <3>; /* 1.8V (L11) */

qcom,src-sel = <0>; /* QPNP_PIN_SEL_FUNC_CONSTANT */

qcom,pull = <1>; /* No Pull */

qcom,master-en = <1>; /*Enable GPIO*/

status = "ok";

};

};

3.dts禁掉smb358-charger，启用usb_detect

smb358_otg_vreg: smb358-charger@57 {

status = "disabled";

};

usb_detect {

compatible = "qcom,gpio-usbdetect";

interrupt-parent = <&spmi_bus>;

interrupts = <0x0 0xA1 0x0>; /* PMD9607 MPP 2 */

interrupt-names = "vbus_det_irq";

};

执行结果
