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 Phil Edworthy (2): dt-bindings: usb: renesas, usb3-peri: Document RZ/V2M r9a09g011 support usb: gadget: udc: renesas_usb3: Add support for RZ/V2M .../bindings/usb/renesas,usb3-peri.yaml | 99 +++++++++++-- drivers/usb/gadget/udc/renesas_usb3.c | 131 ++++++++++++++---- 2 files changed, 188 insertions(+), 42 deletions(-)
