Subject: [PATCH v3 00/15] usb: Add host and device support for RZ/A2
Date: Tue, 14 May 2019 09:55:50 -0500	[thread overview]
Message-ID: <20190514145605.19112-1-chris.brandt@renesas.com> (raw)


NOTE:
This series requires the follow patch from Shimoda-san.
  [PATCH v2] usb: renesas_usbhs: Use specific struct instead of USBHS_TYPE_* enums


For the most part, the RZ/A2 has the same USB 2.0 host and device
HW as the R-Car Gen3, so we can reuse a lot of the code.

However, there are a couple extra register bits, and the CFIFO
register 8-bit access works a little different.

There is a dedicated DMAC for the RZ/A2 USB Device HW, but we
have not been able to reliably get that working yet, so device
operation is pio only at the moment.

On the RZ/A2M eval board, both USB channels can be used as either
host or device. But, it's not set up for otg (ie, there are jumpers
and separate connectors). Therefore, below is an example of what it
would look like to enable USB channel 0 as a device instead of a host.

&usb2_phy0 {
	pinctrl-names = "default";
	pinctrl-0 = <&usb0_pins>;
	dr_mode = "peripheral";
	status = "okay";
};

&usbhs0 {
	status = "okay";
};
