From 8e33f91a0b84ae1964bef77cb92f5d41d97530c8 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 15 Apr 2014 17:06:34 +0100 Subject: clk: shmobile: clk-mstp: change to using clock-indices With the addition of clock-indices, we need to change the renesas clock implementation to use these instead of the local definition of "renesas,clock-indices". Since this will break booting with older device trees, we add a simple auto-detection of which properties are present.
