+STM32 multifunctions timer driver
+
+stm32 timer MFD allow to handle at the same time pwm and IIO timer devices
+
+Required parameters:
+- compatible: must be one of the follow value:
+	"st,stm32-mfd-timer1"
+	"st,stm32-mfd-timer2"
+	"st,stm32-mfd-timer3"
+	"st,stm32-mfd-timer4"
+	"st,stm32-mfd-timer5"
+	"st,stm32-mfd-timer6"
+	"st,stm32-mfd-timer7"
+	"st,stm32-mfd-timer8"
+	"st,stm32-mfd-timer9"
+	"st,stm32-mfd-timer10"
+	"st,stm32-mfd-timer11"
+	"st,stm32-mfd-timer12"
+	"st,stm32-mfd-timer13"
+	"st,stm32-mfd-timer14"
+
+- reg :			Physical base address and length of the controller's
+			registers.
+- clock-names: 		Set to "mfd_timer_clk".
+- clocks: 		Phandle of the clock used by the timer module.
+			For Clk properties, please refer to [1].
+- interrupts :		Reference to the timer interrupt
+
+Optional parameters:
+- resets :		Reference to a reset controller asserting the timer
+
+Optional subnodes:
+- pwm:			See Documentation/devicetree/bindings/pwm/pwm-stm32.txt
+- iiotimer:		See Documentation/devicetree/bindings/iio/timer/stm32-iio-timer.txt
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Example:
+	mfd_timer1: mfdtimer1@40010000 {
+		compatible = "st,stm32-mfd-timer1";
+		reg = <0x40010000 0x400>;
+		clocks = <&rcc 0 160>;
+		clock-names = "mfd_timer_clk";
+		interrupts = <27>;
+
+		pwm1: pwm1@40010000 {
+			compatible = "st,stm32-pwm1";
+		};
+
+		iiotimer1: iiotimer1@40010000 {
+			compatible = "st,stm32-iio-timer1";
+		};
+	};
