USB - HSIC support in IMX7D SabreSD

[gopinathsriniva]

Hi,

I am trying to use USB - HSIC in IMX7D sabreSD development board. I have connected an EVB-USB3503 CSP chip from third party vendor and tried to use USB. But it seems support for USB-HSIC is not there in the kernel. Any ideas on how to enable USB-HSIC support in IMX7 SabreSD?

Hi Gopinath

please check phy_type property, pinctrl-names for hsic in
linux/Documentation/devicetree/bindings/usb/ci-hdrc-imx.txt
and one can debug it in linux/drivers/usb/chipidea/ci_hdrc_imx.c

Best regards
igor
