-* Exynos5422 frequency and voltage scaling for Dynamic Memory Controller device
-
-The Samsung Exynos5422 SoC has DMC (Dynamic Memory Controller) to which the DRAM
-memory chips are connected. The driver is to monitor the controller in runtime
-and switch frequency and voltage. To monitor the usage of the controller in
-runtime, the driver uses the PPMU (Platform Performance Monitoring Unit), which
-is able to measure the current load of the memory.
-When 'userspace' governor is used for the driver, an application is able to
-switch the DMC and memory frequency.
-
-Required properties for DMC device for Exynos5422:
-- compatible: Should be "samsung,exynos5422-dmc".
-- clocks : list of clock specifiers, must contain an entry for each
-  required entry in clock-names for CLK_FOUT_SPLL, CLK_MOUT_SCLK_SPLL,
-  CLK_FF_DOUT_SPLL2, CLK_FOUT_BPLL, CLK_MOUT_BPLL, CLK_SCLK_BPLL,
-  CLK_MOUT_MX_MSPLL_CCORE, CLK_MOUT_MX_MSPLL_CCORE_PHY, CLK_MOUT_MCLK_CDREX,
-- clock-names : should include "fout_spll", "mout_sclk_spll", "ff_dout_spll2",
-  "fout_bpll", "mout_bpll", "sclk_bpll", "mout_mx_mspll_ccore",
-  "mout_mclk_cdrex"  entries
-- devfreq-events : phandles for PPMU devices connected to this DMC.
-- vdd-supply : phandle for voltage regulator which is connected.
-- reg : registers of two CDREX controllers.
-- operating-points-v2 : phandle for OPPs described in v2 definition.
-- device-handle : phandle of the connected DRAM memory device. For more
-	information please refer to documentation file:
-	Documentation/devicetree/bindings/ddr/lpddr3.txt
-- devfreq-events : phandles of the PPMU events used by the controller.
-- samsung,syscon-clk : phandle of the clock register set used by the controller,
-	these registers are used for enabling a 'pause' feature and are not
-	exposed by clock framework but they must be used in a safe way.
-	The register offsets are in the driver code and specyfic for this SoC
-	type.
-
-Optional properties for DMC device for Exynos5422:
-- interrupt-parent : The parent interrupt controller.
-- interrupts : Contains the IRQ line numbers for the DMC internal performance
-  event counters in DREX0 and DREX1 channels. Align with specification of the
-  interrupt line(s) in the interrupt-parent controller.
-- interrupt-names : IRQ names "drex_0" and "drex_1", the order should be the
-  same as in the 'interrupts' list above.
-
-Example:
-
-	ppmu_dmc0_0: ppmu@10d00000 {
-		compatible = "samsung,exynos-ppmu";
-		reg = <0x10d00000 0x2000>;

-			ppmu_event_dmc0_0: ppmu-event3-dmc0_0 {
-				event-name = "ppmu-event3-dmc0_0";
-			};
-		};
