[PATCH 3/4] arm64: dts: Move NS2 clock DT nodes to separate DT file

Anup Patel anup.patel at broadcom.com
Tue Mar 29 00:27:33 PDT 2016


For more readabilty and consistency with other Broadcom SoCs, we move
all NS2 clock DT nodes from main SoC DT file to a separate DT file.

We also update the license header in ns2.dtsi as-per new Broadcom
convention.
