Hi all, This is v4 of the patch set which adds support of Dynamic Memory Controller for Exynos5422 SoC. The driver supports Dynamic Voltage and Frequency Scalling for the DMC and DRAM. It also provides needed timings for different speed operations of the DRAM memory. The patch set is based on tag: v5.0-rc4 changes: v4: - removed unneeded DPLL and G3D clocks IDs - changed names of parent clocks for mout_mx_mspll_ccore_phy_p and added one more parent: mout_sclk_epll - removed 933Mhz and 138MHz from the BPLL ratio table v3: - in DTS align to proper indent the clocks and clock-names entries v2: - changed file name exynos5-dmc.c -> exynos5422-dmc.c and related entries in other files - changed dt-binding file name - changed config entry to CONFIG_ARM_EXYNOS5422_DMC_DEVFREQ - removed sysfs and print info messages (print only one line) - removed function exynos5_read_chip_info and compact code - changed dt-binding patch and move it up in the patch set - new entries in MAINTAINERS are added with the driver c code - clean-up in DTS file: renamed nodes to 'ppmu' and 'memory-controller', entries moved to suggested location (before nocp nodes or after), moved according to alfabetical order, compacted clocks names with right indent.
