Hi Kishon,
Would you pick up this patch?
Without this patch, passing a const struct phy_ops* to ulip_phy_create will
have compiler warning.
It should be fine to pass a const struct phy_ops* to

I didn't intend to change anything. This works fine for me.
Maybe proper rounding would be a nice addition, but I'm not sure if

This commit fixes the following issues:
1. The 9th bit of buf was believed to be the LSB of divisor's
exponent, but the hardware interprets it as MSB (9th bit) of the
mantissa. The exponent is actually one bit shorter and applies
to base 4, not 2 as previously believed.
2. Loop iterations double

Hi,
We have designed a h/w system with the Renesas USB 3.0 upd7202 controller.

As a result lsusb doesn't report the USB3.0 ports.
Adding traces to the kernel we could see that this is happening in
