These patch-set adds the generic exynos bus frequency driver for memory bus with DEVFREQ framework. The Samsung Exynos SoCs have the common architecture for memory bus between DRAM memory and MMC/sub IP in SoC. This driver can support the memory bus frequency driver for Exynos SoCs. Each memory bus block has a clock for memory bus speed and frequency table which is changed according to the utilization of memory bus on runtime. And then each memory bus group has the one more memory bus blocks and OPP table (including frequency and voltage), regulator, devfreq-event devices. There are a little difference about the number of memory bus because each Exynos SoC have the different sub-IP and different memory bus speed. In spite of this difference among Exynos SoCs, we can support almost Exynos SoC by adding unique data of memory bus to devicetree file.
