[PATCH 5.10.y-cip 05/13] arm64: dts: renesas: r9a07g044c2-smarc: Enable usb2.0


Biju Das
 

commit 1889f4798c443dfd4993ba9bbbf4ed7bf801d94b upstream.

Enable usb2.0 host/device functionality on RZ/G2LC SMARC EVK
by deleting phyrst, usb2_phy{0,1}, ehci/ohci{0,1} and hsusb
entries from board DT, so that entries from common dtsi kick
in and make USB2.0 functionality operational.
