Hi,

The RZ/V2M SoC is very similar to the R-Car implementation.
The differences are that a few DRD related registers and bits have
moved, there is a separate interrupt for DRD, an additional clock for
register access and reset lines for DRD and USBP.

Thanks
Phil

v3:
bindings:
 - Keep the existing constraints by adding an 'else' clause with
   'maxItems: 1' for various properties.
driver:
 - The ramsize_per_ramif specifies the amount of ram for
   IN _or_ OUT pipes, not combined, so it should be 16KB.
 - When changing role, ensure only one of host/perip reset is deasserted
 - Correct number of pipes to 16. The driver will calculate the nr
   of pipes to use based on the available ram and ramsize_per_pipe.

v2:
bindings:
 - SoCs other than rz/v2m must limit the number of clock/interrupt names
 - Add "Battery Charging" and "Global Purpose Input" interrupts
driver:
 - Rename r9a09g011 feature to is_rzv2m; use rzv2m compat string
 - Pass pointer into macros that access is_rzv2m member
