Four of these starting at USBPHY1_ADDR means the last one clashes with what we define as "FSL_IMX6_SNVSHP_ADDR 0x020CC000". I only have the i.MX 6Dual/6Quad reference manual to hand, so maybe this imx6 variant is different, but that document says there are 4 USB controllers but only 2 PHY blocks. thanks -- PMM

Good catch. I'll re-check the datsheet and send an updated patch. Thanks, Guenter
