HSIC I/F USB PHY information for i.MX6

Dear all,

We want to use USB Host port2 and Host port3 of i.MX6.

However, i.MX6 does not have Internal PHY for Host2 and Host3.

These Host ports are HSIC I/F and need external PHY.

Is there the HSIC I/F USB PHY with the operating experience?

Would you tell me a maker and the model number?

Is the sample driver for these PHY included in LinuxBSP?

(fsl-yocto-L3.14.52_1.1.0-ga.tar)

May I have advice?

Best Regards,

Yuuki

Dear Igor-san,

Thank you for your support.

Please tell me one more.

Is the sample driver of USB3503A included, too?

Is a driver modification necessary for USB3503A?

Best Regards,

Yuuki
