1862ceabbSDavid Lechner* Device tree bindings for Texas Instruments DaVinci timer 2862ceabbSDavid Lechner 3862ceabbSDavid LechnerThis document provides bindings for the 64-bit timer in the DaVinci 4862ceabbSDavid Lechnerarchitecture devices. The timer can be configured as a general-purpose 64-bit 5862ceabbSDavid Lechnertimer, dual general-purpose 32-bit timers. When configured as dual 32-bit 6862ceabbSDavid Lechnertimers, each half can operate in conjunction (chain mode) or independently 7862ceabbSDavid Lechner(unchained mode) of each other. 8862ceabbSDavid Lechner 9862ceabbSDavid LechnerThe timer is a free running up-counter and can generate interrupts when the 10862ceabbSDavid Lechnercounter reaches preset counter values. 11862ceabbSDavid Lechner 12862ceabbSDavid LechnerAlso see ../watchdog/davinci-wdt.txt for timers that are configurable as 13862ceabbSDavid Lechnerwatchdog timers. 14862ceabbSDavid Lechner 15862ceabbSDavid LechnerRequired properties: 16862ceabbSDavid Lechner 17862ceabbSDavid Lechner- compatible : should be "ti,da830-timer". 18862ceabbSDavid Lechner- reg : specifies base physical address and count of the registers. 19862ceabbSDavid Lechner- interrupts : interrupts generated by the timer. 20862ceabbSDavid Lechner- interrupt-names: should be "tint12", "tint34", "cmpint0", "cmpint1", 21862ceabbSDavid Lechner "cmpint2", "cmpint3", "cmpint4", "cmpint5", "cmpint6", 22862ceabbSDavid Lechner "cmpint7" ("cmpintX" may be omitted if not present in the 23862ceabbSDavid Lechner hardware). 24862ceabbSDavid Lechner- clocks : the clock feeding the timer clock. 25862ceabbSDavid Lechner 26862ceabbSDavid LechnerExample: 27862ceabbSDavid Lechner 28862ceabbSDavid Lechner clocksource: timer@20000 { 29862ceabbSDavid Lechner compatible = "ti,da830-timer"; 30862ceabbSDavid Lechner reg = <0x20000 0x1000>; 31862ceabbSDavid Lechner interrupts = <21>, <22>, <74>, <75>, <76>, <77>, <78>, <79>, 32862ceabbSDavid Lechner <80>, <81>; 33862ceabbSDavid Lechner interrupt-names = "tint12", "tint34", "cmpint0", "cmpint1", 34862ceabbSDavid Lechner "cmpint2", "cmpint3", "cmpint4", "cmpint5", 35862ceabbSDavid Lechner "cmpint6", "cmpint7"; 36862ceabbSDavid Lechner clocks = <&pll0_auxclk>; 37862ceabbSDavid Lechner }; 38
