Subject: [PATCH v4 4/4] ARM: dts: enable PCIe support for Cygnus
Date: Mon, 9 Mar 2015 17:21:17 -0700	[thread overview]
Message-ID: <1425946878-13169-5-git-send-email-rjui@broadcom.com> (raw)
In-Reply-To: <1425946878-13169-1-git-send-email-rjui@broadcom.com>

Add PCIe device nodes in bcm-cygnus.dtsi but keep them disabled there.
Only enable them for bcm958300k where PCIe interfaces are populated
