From 0722249ac1f3dcc3af9e9d7ed89792a68f066660 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Tue, 3 Nov 2015 19:04:16 +0900 Subject: PM / devfreq: exynos: Add generic exynos bus frequency driver This patch adds the generic exynos bus frequency driver for AMBA AXI bus of sub-blocks in exynos SoC with DEVFREQ framework. The Samsung Exynos SoC have the common architecture for bus between DRAM and sub-blocks in SoC. This driver can support the generic bus frequency driver for Exynos SoCs. In devicetree, Each bus block has a bus clock, regulator, operation-point and devfreq-event devices which measure the utilization of each bus block.
