Hi Stephen,

ID pins are connected to pcf8575, and the pcf8575's interrupt line is

gpio bank6 pin 11, we use this gpio interrupt to detect the ID pin

In that case, the PCF8575 node needs to be a GPIO controller and an IRQ
controller, as does the driver for the PCF8575. This binding should have
a single entry in the gpios property, and the driver can call
gpio_to_irq() on that so it knows which IRQ to request.
You meant some thing like this?
pcf_usb: pcf8575@21 {
compatible = "ti,pcf8575";
reg = <0x21>;
gpio-controller;
#gpio-cells = <2>;
interrupt-parent = <&gpio6>;
interrupts = <11 2>;
interrupt-controller;
#interrupt-cells = <2>;
};
usb_vid_gpio {
compatible = "ti,dra7xx-usb";
gpios = <&pcf_usb 1 0>;
};
Yes.
Except that the compatible value for the usb_vid_gpio node still looks
wrong, since I think that node isn't anything to do with any particular SoC.
Yes will fix that too in v2.
