Subject: [PATCH 458/469] dt-bindings: usb: rockchip,dwc3: Add RK3588 binding
|
|
|
|
RK3588 contains three DWC3 cores. Two of them are connected to
|
|
dedicated USBDP PHY and can be used in dual-role. The third is
|
|
connected to one of the shared combo PHYs used for PCIe/SATA/USB3
|
|
and can only be used in host mode. Since the binding is all about
|
|
the PHY glueing and involved clocks, separate compatible values
|
|
have been created for these two types.
