This patch adds common USB phy ports initializer for r8a7779.

The note is that each USB IP have own MSTP clock bit,
and common USB phy port doesn't have MSTP clock,
but this USB phy needs USB clock.
Each USB driver / platform should keep USB MSTP clock somehow.

Shouldn't the USB PHY driver go to drivers/usb/phy/ or
drivers/usb/host/ehci-sh.c?

We are trying hard to move driver code out of the platform and into driver
directories these days, and having it wired up as part of the platform
the way you do also means it is always powered on.

I see.
I can move this code to under driver.
Can I send additional patch for it ?
 - move usb phy code to driver (to Simon, USB ML)

Or should I send multi patches ?
 - remove this patch (to Simon)
 - add usb phy driver patch (to USB ML)
 - use usb phy driver patch (to Simon)

I think that the best approach would be for
a) me to remove the patches in question from your tree
b) you to send fresh patches, perhaps the USB ones need
   to go through another tree (= other than my renesas tree)
c) I will send a fresh pull request.

I am guessing this may take a little time. If so, as the end of opportunity
to get fresh code into 3.7 is approaching I may post an intermediate pull
request that omits the USB changes.

I see neither big-endian support on shmobile, nor any XHCI (USB-3.0) driver, just
the old EHCI (USB-2.0) and OHCI (USB-1.1) drivers. Are you submitting the XHCI
support and big-endian platform code separately?

Sorry for very confusing naming.
I fix it

Best regards
