From: Rajendra Nayak Date: Tue, 29 Apr 2014 11:05:10 +0000 (+0530) Subject: ARM: dts: Add support for DRA72x family of devices X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=38b248db60e32734417534b57f9ab687c445113a;p=deliverable%2Flinux.git ARM: dts: Add support for DRA72x family of devices DRA722 is part of DRA72x family which are single core cortex A15 devices with most infrastructure IPs otherwise same as whats on the DRA74x family. So move the cpu nodes into dra74x.dtsi and dra72x.dtsi respectively. Also add a minimal dra72-evm dts file.
