162306a36Sopenharmony_ci* Device tree bindings for Texas instruments Keystone timer 262306a36Sopenharmony_ci 362306a36Sopenharmony_ciThis document provides bindings for the 64-bit timer in the KeyStone 462306a36Sopenharmony_ciarchitecture devices. The timer can be configured as a general-purpose 64-bit 562306a36Sopenharmony_citimer, dual general-purpose 32-bit timers. When configured as dual 32-bit 662306a36Sopenharmony_citimers, each half can operate in conjunction (chain mode) or independently 762306a36Sopenharmony_ci(unchained mode) of each other. 862306a36Sopenharmony_ci 962306a36Sopenharmony_ciIt is global timer is a free running up-counter and can generate interrupt 1062306a36Sopenharmony_ciwhen the counter reaches preset counter values. 1162306a36Sopenharmony_ci 1262306a36Sopenharmony_ciDocumentation: 1362306a36Sopenharmony_cihttps://www.ti.com/lit/ug/sprugv5a/sprugv5a.pdf 1462306a36Sopenharmony_ci 1562306a36Sopenharmony_ciRequired properties: 1662306a36Sopenharmony_ci 1762306a36Sopenharmony_ci- compatible : should be "ti,keystone-timer". 1862306a36Sopenharmony_ci- reg : specifies base physical address and count of the registers. 1962306a36Sopenharmony_ci- interrupts : interrupt generated by the timer. 2062306a36Sopenharmony_ci- clocks : the clock feeding the timer clock. 2162306a36Sopenharmony_ci 2262306a36Sopenharmony_ciExample: 2362306a36Sopenharmony_ci 2462306a36Sopenharmony_citimer@22f0000 { 2562306a36Sopenharmony_ci compatible = "ti,keystone-timer"; 2662306a36Sopenharmony_ci reg = <0x022f0000 0x80>; 2762306a36Sopenharmony_ci interrupts = <GIC_SPI 110 IRQ_TYPE_EDGE_RISING>; 2862306a36Sopenharmony_ci clocks = <&clktimer15>; 2962306a36Sopenharmony_ci}; 30
