Subject: [PATCH] dt-bindings: timer: Convert cirrus,clps711x-timer to DT schema
Convert the Cirrus CLPS711x timer binding to DT schema format. It's a
straight-forward conversion.
Drop the aliases node and second example which aren't relevant.

-* Cirrus Logic CLPS711X Timer Counter
-
-Required properties:
-- compatible: Shall contain "cirrus,ep7209-timer".
-- reg : Address and length of the register set.
-- interrupts: The interrupt number of the timer.
-- clocks : phandle of timer reference clock.
-
-Note: Each timer should have an alias correctly numbered in "aliases" node.
-
-Example:
- aliases {
- timer0 = &timer1;
- timer1 = &timer2;
- };
-
- timer1: timer@...00300 {
- compatible = "cirrus,ep7312-timer", "cirrus,ep7209-timer";
- reg = <0x80000300 0x4>;
- interrupts = <8>;
- clocks = <&clks 5>;
- };
-
- timer2: timer@...00340 {
- compatible = "cirrus,ep7312-timer", "cirrus,ep7209-timer";
- reg = <0x80000340 0x4>;
- interrupts = <9>;
- clocks = <&clks 6>;
- };
