I meant that both the driver and DT schema expects it to be uint32, while the dts has got the property as boolean, which is wrong. The same problem has been fixed in the Amlogic Meson-g12 DT schema example: https://lore.kernel.org/linux-usb/20201014101402.18271-1-Sergey.Semin@baikalelectronics.ru/T/#m225585212162b9f5cccb1a7088850fab8792b7b3 -Sergey > > Best regards, > Krzysztof

In accordance with the DWC USB3 bindings the property is supposed to have uint32 type. It's erroneous from the DT schema and driver points of view to declare it as boolean. As Neil suggested set it to 0x20 so not break the platform and to make the dtbs checker happy.
