I.MX7D - USB HSIC support in SabreSD

[gopinathsriniva]

Hi,

I have enabled the USB3503 HSIC support in MCIMX7SABRE board by adding below node in dts file. 

usbh: usb@30b30000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b30000 0x200>;
interrupts = <GIC_SPI 40 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX7D_USB_CTRL_CLK>;
fsl,usbphy = <&usbphy_nop3>;
fsl,usbmisc = <&usbmisc3 0>;
phy_type = "hsic";
dr_mode = "host";
phy-clkgate-delay-us = <400>;
status = "okay";
};

After this, HSIC driver is loaded successfully. But  I am getting below error message always.

Can you please tell me, Is there any other driver support needed for USB3503 HSIC EVM board? Any ideas how to proceed on this issue?
