1926b65e2SIvan Khoronzhuk* Device tree bindings for Texas instruments Keystone timer 2926b65e2SIvan Khoronzhuk 3926b65e2SIvan KhoronzhukThis document provides bindings for the 64-bit timer in the KeyStone 4926b65e2SIvan Khoronzhukarchitecture devices. The timer can be configured as a general-purpose 64-bit 5926b65e2SIvan Khoronzhuktimer, dual general-purpose 32-bit timers. When configured as dual 32-bit 6926b65e2SIvan Khoronzhuktimers, each half can operate in conjunction (chain mode) or independently 7926b65e2SIvan Khoronzhuk(unchained mode) of each other. 8926b65e2SIvan Khoronzhuk 9926b65e2SIvan KhoronzhukIt is global timer is a free running up-counter and can generate interrupt 10926b65e2SIvan Khoronzhukwhen the counter reaches preset counter values. 11926b65e2SIvan Khoronzhuk 12926b65e2SIvan KhoronzhukDocumentation: 13dcf30fc0SAlexander A.
