Date: Sat, 15 Nov 2014 16:17:42 -0800 From: Kevin Cernekee <cernekee@...il.com> To: ralf@...ux-mips.org Cc: f.fainelli@...il.com, jfraser@...adcom.com, dtor@...omium.org, tglx@...utronix.de, jason@...edaemon.net, linux-mips@...ux-mips.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH V2 18/22] MIPS: Create a helper function for DT setup A couple of platforms register two buses and call of_platform_populate(). Move this into a common function to reduce duplication.
