From: Gustavo Pimentel Date: Tue, 15 May 2018 14:41:41 +0000 (+0100) Subject: dt-bindings: PCI: designware: Example update X-Git-Tag: v4.19~864^2~12^2~7 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=467c7a7376421176ac248d93c65182847001cfbd;p=platform%2Fkernel%2Flinux-rpi3.git dt-bindings: PCI: designware: Example update Replace "ctrlreg" reg-name by "dbi" to be coherent with similar drivers, however it still be compatible with any previous DT that uses the old reg-name. Replace the PCIe base address example by a real PCIe base address in use.
