[PATCH v2 4/9] ARM: dts: bcm2711: Add reset controller to xHCI node

From: Nicolas Saenz Julienne <hidden>
Date: 2020-06-09 18:16:44
Also in: linux-devicetree, linux-pci, linux-usb, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

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.

Signed-off-by: Nicolas Saenz Julienne <redacted>
