-* NXP LPC3220 timer
-
-The NXP LPC3220 timer is used on a wide range of NXP SoCs. This
-includes LPC32xx, LPC178x, LPC18xx and LPC43xx parts.
-
-Required properties:
-- compatible:
-	Should be "nxp,lpc3220-timer".
-- reg:
-	Address and length of the register set.
-- interrupts:
-	Reference to the timer interrupt
-- clocks:
-	Should contain a reference to timer clock.
-- clock-names:
-	Should contain "timerclk".
-
-Example:
-
-timer1: timer@...85000 {
-	compatible = "nxp,lpc3220-timer";
-	reg = <0x40085000 0x1000>;
-	interrupts = <13>;
-	clocks = <&ccu1 CLK_CPU_TIMER1>;
-	clock-names = "timerclk";
-};
