I have development board whose SoC is exynos4412, I try to enable the
usb in it but I failed. I saw the document
Documentation/devicetree/bindings/usb/samsung-usbphy.txt, does it mean
that the usb driver is not done?
And about that document, in samsung datasheet(32.8.2), the address reg
0x125B_0000 + 32bits contains hsic1, hsic0, phy1 and phy0's power
control. And in 0x1002_0704 + 3 * 32 bits, it contains usb_phy,
hsic1_phy and hsic2_phy control(8.8.1.27). So I doubt the documents.
Here is the log and dts
