dt-bindings: timer: ti,davinci-timer: convert to dtschema
Convert txt binding of TI's DaVinci timer to dtschema to allow for
validation.
While at it, change the file name to match the compatible.

This is a 64-bit timer found on TI's DaVinci architecture devices. The timer
14
+
can be configured as a general-purpose 64-bit timer, dual general-purpose
15
+
32-bit timers. When configured as dual 32-bit timers, each half can operate
16
+
in conjunction (chain mode) or independently (unchained mode) of each other.
17
+
18
+
The timer is a free running up-counter and can generate interrupts when the
19
+
counter reaches preset counter values.

* Device tree bindings for Texas Instruments DaVinci timer

-
This document provides bindings for the 64-bit timer in the DaVinci
4
-
architecture devices. The timer can be configured as a general-purpose 64-bit
5
-
timer, dual general-purpose 32-bit timers. When configured as dual 32-bit
6
-
timers, each half can operate in conjunction (chain mode) or independently
7
-
(unchained mode) of each other.
8
-
9
-
The timer is a free running up-counter and can generate interrupts when the
10
-
counter reaches preset counter values.
11
-
12
-
Also see ../watchdog/davinci-wdt.txt for timers that are configurable as
13
-
watchdog timers.
14
-
15
-
Required properties:
16
-
17
-
- compatible : should be "ti,da830-timer".
18
-
- reg : specifies base physical address and count of the registers.
19
-
- interrupts : interrupts generated by the timer.
20
-
- interrupt-names: should be "tint12", "tint34", "cmpint0", "cmpint1",
21
-
"cmpint2", "cmpint3", "cmpint4", "cmpint5", "cmpint6",
22
-
"cmpint7" ("cmpintX" may be omitted if not present in the
23
-
hardware).
24
-
- clocks : the clock feeding the timer clock.
25

Example:
27
-
28
-
clocksource: timer@20000 {
29
-
compatible = "ti,da830-timer";
30
-
reg = <0x20000 0x1000>;
31
-
interrupts = <21>, <22>, <74>, <75>, <76>, <77>, <78>, <79>,
32
-
<80>, <81>;
33
-
interrupt-names = "tint12", "tint34", "cmpint0", "cmpint1",
34
-
"cmpint2", "cmpint3", "cmpint4", "cmpint5",
35
-
"cmpint6", "cmpint7";
