[PATCH 0/4] arm64: dts: renesas: r8a77995 and draak: add USB2.0 Host

[PATCH 0/4] arm64: dts: renesas: r8a77995 and draak: add USB2.0 Host

[Yoshihiro Shimoda]

This patch set is based on the renesas-drivers.git /
renesas-drivers-2017-09-05-v4.13 tag.

The R-Car D3 USB2.0 PHY binding patch is not merged yet. But, this driver
can be probed and work by using fallback compatible value.

This patch set needs the following pinctrl patch:
 "[PATCH v2] pinctrl: sh-pfc: r8a77995: Add USB2.0 host support"

Otherwise, USB2.0 PHY driver cannot be probed.


Yoshihiro Shimoda (4):
  arm64: dts: renesas: r8a77995: Add USB2.0 PHY device node
  arm64: dts: renesas: r8a77995: add USB2.0 Host (EHCI/OHCI) device node
  arm64: dts: renesas: r8a77995: draak: enable USB2.0 PHY
  arm64: dts: renesas: r8a77995: draak: enable USB2.0 Host (EHCI/OHCI)
