From 8e63ed518dd6f03119b58af40b5f1e5bae688121 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Thu, 2 Feb 2017 15:01:37 +0530 Subject: arch: arm: update the IFC IP input clock IFC IP clock is always a constant divisor of platform clock pre-defined per SoC. Clock control register (CCR) used in current implementation governs IFC IP output clock. Update sys_info->freq_localbus to represent IFC input clock with value constant divisor of platform clock.
