X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b6b74087f90a201cfdd6da6a43e7b92dba8370e3;p=thirdparty%2Flinux.git

arm64: dts: rockchip: Enable USB 2.0 ports on ArmSoM Sige1

The ArmSoM Sige1 has two USB 2.0 Type-A HOST ports behind an onboard
USB hub, and one USB 2.0 Type-C OTG port.

Add support for using the USB 2.0 ports on ArmSoM Sige1.

The onboard USB hub handles OHCI so only the EHCI controller is enabled.
