6100ef093b phy: rcar-gen3-usb2: add binding for r8a77995
This patch adds binding for r8a77995 (R-Car D3). Since r8a77995 doesn't
have dedicated pins (ID, VBUS), this will match against the generic
fallback on R-Car D3.

For now, this driver doesn't support usb role swap for r8a77995.

cde7bc367f phy: rcar-gen3-usb2: add fallback binding
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that its not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

b956401699 phy: rcar-gen3-usb2: remove HSUSB registers handling
Since the related driver (CPG/MSSR driver) only manages the first module
clock, this driver should not handle the HSUSB registers. So, this patch
removes the HSUSB registers handling.

9f391c574e phy: rcar-gen3-usb2: add runtime ID/VBUS pin detection
This patch adds support for runtime ID/VBUS pin detection if
the channel 0 of R-Car gen3 is used. So, we are able to use
the channel as both host and peripheral.

f3b5a8d9b5 phy: rcar-gen3-usb2: Add R-Car Gen3 USB2 PHY driver
This patch adds support for R-Car generation 3 USB2 PHY driver.
This SoC has 3 EHCI/OHCI channels, and the channel 0 is shared
with the HSUSB (USB2.0 peripheral) device. And each channel has
independent registers about the PHYs.

So, the purpose of this driver is:
 1) initializes some registers of SoC specific to use the
    {ehci,ohci}-platform driver.

 2) detects id pin to select host or peripheral on the channel 0.

For now, this driver only supports 1) above.
