[PATCH 4/9] ARM: dts: bcm2711: Add reset controller to xHCI node

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The chip is hardwired to the board's PCIe bus and needs to be properly
setup trough a firmware routine after a PCI fundamental reset. Pass the
reset controller phandle that takes care of triggering the
initialization to the relevant PCI device.
