-* Device tree bindings for Texas instruments Keystone timer
-
-This document provides bindings for the 64-bit timer in the KeyStone
-architecture devices. The timer can be configured as a general-purpose 64-bit
-timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
-timers, each half can operate in conjunction (chain mode) or independently
-(unchained mode) of each other.
-
-It is global timer is a free running up-counter and can generate interrupt
-when the counter reaches preset counter values.
-
-Documentation:
-https://www.ti.com/lit/ug/sprugv5a/sprugv5a.pdf
-
-Required properties:
-
-- compatible : should be "ti,keystone-timer".
-- reg : specifies base physical address and count of the registers.
-- interrupts : interrupt generated by the timer.
-- clocks : the clock feeding the timer clock.
-
-Example:
-
-timer@22f0000 {
-	compatible = "ti,keystone-timer";
-	reg = <0x022f0000 0x80>;
-	interrupts = <GIC_SPI 110 IRQ_TYPE_EDGE_RISING>;
-	clocks = <&clktimer15>;
-};
