Subject: Re: RK3288 USB Issues

Hi,

I built a kernel with the sources from your branch, and the problem is
gone. Looking at the differences I had added the reset to the wrong
usb port in the dtb (phy1 instead of phy 2)

Thanks for your help figuring this out

usbphy1: usb-phy@334 {
#phy-cells = <0>;
reg = <0x334>;
clocks = <&cru SCLK_OTGPHY1>;
clock-names = "phyclk";
#clock-cells = <0>;
resets = <&cru SRST_USBHOST1_PHY>;
reset-names = "phy-reset";
};
