Subject: [PATCH v3 4/9] ARM: dts: bcm2711: Add reset controller to xHCI node
Date: Fri, 12 Jun 2020 19:13:28 +0200 [thread overview]
Message-ID: <20200612171334.26385-5-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200612171334.26385-1-nsaenzjulienne@suse.de>
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.
