- only keep one compatible string

+STM32 General Purpose Timer driver bindings
+
+Required parameters:
+- compatible: must be "st,stm32-gptimer"
+
+- reg: Physical base address and length of the controller's
+ registers.
+- clock-names: Set to "clk_int".
+- clocks: Phandle to the clock used by the timer module.
+ For Clk properties, please refer to
../clock/clock-bindings.txt
+
+Optional parameters:
+- resets: Phandle to the parent reset controller.
+ See ../reset/st,stm32-rcc.txt
+
+Optional subnodes:
+- pwm: See ../pwm/pwm-stm32.txt
+- timer: See ../iio/timer/stm32-timer-trigger.txt
+
+Example:
+ timers@40010000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "st,stm32-gptimer";
+ reg = <0x40010000 0x400>;
+ clocks = <&rcc 0 160>;
+ clock-names = "clk_int";
+
+ pwm@0 {
+ compatible = "st,stm32-pwm";
+ pinctrl-0 = <&pwm1_pins>;
+ pinctrl-names = "default";
+ };
+
+ timer@0 {
+ compatible = "st,stm32-timer-trigger";
+ reg = <0>;
+ };
+ };
