With <0x10050230 0x4> added to usbphy-sys in exynos5250.dtsi file, s3c-usbphy doesn't complain anymore. However I still can't find my usb3 device, which might be a configuration issue.

I tested Linaro 13.04 kernel on my Exynos5250 and found that USB device is not found (i.e. nothing in lsusb). It used to work with Linaro 13.01. dmesg showed that s3c-usbphy can't configure phy mode (see below). Looking at the samsung-usbphy.c file, it looks like sysreg is not defined in device tree file. I am thinking that we are missing one parameter for usbphy-sys in the exynos5250.dtsi, by comparing a patch from
http://comments.gmane.org/gmane.linux.usb.general/82597.
Thanks for the catch. I will update the same in Linaro kernel.
Do you get usb to working for you when you apply the additional reg entry?
