19f9e188de usb: phy: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

fda7130354 usb: phy: don't check resource with devm_ioremap_resource
devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

54407f190c phy-rcar-usb: add R8A7778 support
The driver currently only supports R8A7779 SoC. Compared to it, R8A7778 USB-PHY
has extra register range containing two high-speed signal quality characteristic
control registers which should be set up  during USB-PHY  startup depending on
whether a ferrite bead is in use or not.  So, we now handle an optional second
memory range in the driver's probe method, add the 'ferrite_bead' field to the
driver's platform data, and add an extra (optional) step to the USB-PHY startup
routine which sets up the extended registers.

Also mark in the driver's Kconfig section  that R8A7778 is now supported and
generally clarify that section, uppercasing the word "phy" and also changing
the module name that got lost in the big driver rename, while at it...

The patch has been tested on the Marzen and BOCK-W boards.

7173e59e6b phy-rcar-usb: handle platform data
Set the USBPCTRL0 register from the passed platform data in rcar_usb_phy_init();
don't reset it to 0 in  rcar_usb_phy_shutdown()  anymore as that does not make
sense.  Also, don't allow the driver's probe to succeed when the platform data
are not supplied with a device.

The patch has been tested on the Marzen and BOCK-W boards.

725bf9dcaf phy-rcar-usb: correct base address
The memory region that is used by the driver overlaps EHCI and OHCI  register
regions for absolutely no reason now  -- fix it  by adding offset of 0x800 to
the base address, changing the register #define's accordingly. This has extra
positive effect that we now can use devm_ioremap_resource()...

Note that the driver and the SoC code have to be in one patch to keep the code
bisectable...

The patch has been tested on the Marzen board.

463c824bb7 phy-rcar-usb: remove EHCI internal buffer setup
Now that the EHCI internal  buffer setup is done by the platform code,  we  can
remove  such code from this driver as it  never  really belonged here.  We also
no longer need the 2nd memory region now (2nd EHCI controller is simply missing
in e.g. R8A7778 SoC).

The patch has been tested on the Marzen and BOCK-W boards.

94ae98433a usb: phy: rename all phy drivers to phy-$name-usb.c
this will make sure that we have sensible names
for all phy drivers. Current situation was already
quite bad with too generic names being used.
