Subject: [PATCH] arm64: dts: juno: Correct PCI IO window
Date: Tue, 29 Nov 2016 14:45:10 -0600 [thread overview]
Message-ID: <1480452310-29286-1-git-send-email-jeremy.linton@arm.com> (raw)
The PCIe root complex on Juno translates the MMIO mapped
at 0x5f800000 to the PIO address range starting at 0
(which is common because PIO addresses are generally < 64k).
Correct the DT to reflect this.
