When you say two PHYs, do you mean the HS PHY and the SS PHY?

Or are there two HS PHYs? If so, would the other HS PHY have a sleep_b clock?

The clock-names property should describe the clocks from the view of the device
itself. As we're describing the PHY in isolation, rather than a big block that
contains the PHY, the presesnce or absence of other PHYs should not affect the
name. If the "_a" suffix is only to differentiate the instance of PHY, it
should be dropped.

Thanks,
Mark.
