1*c66ec88fSEmmanuel Vadot* OMAP PWM for dual-mode timers 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotRequired properties: 4*c66ec88fSEmmanuel Vadot- compatible: Shall contain "ti,omap-dmtimer-pwm". 5*c66ec88fSEmmanuel Vadot- ti,timers: phandle to PWM capable OMAP timer. See timer/ti,timer.txt for info 6*c66ec88fSEmmanuel Vadot about these timers. 7*c66ec88fSEmmanuel Vadot- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of 8*c66ec88fSEmmanuel Vadot the cells format. 9*c66ec88fSEmmanuel Vadot 10*c66ec88fSEmmanuel VadotOptional properties: 11*c66ec88fSEmmanuel Vadot- ti,prescaler: Should be a value between 0 and 7, see the timers datasheet 12*c66ec88fSEmmanuel Vadot- ti,clock-source: Set dmtimer parent clock, values between 0 and 2: 13*c66ec88fSEmmanuel Vadot - 0x00 - high-frequency system clock (timer_sys_ck) 14*c66ec88fSEmmanuel Vadot - 0x01 - 32-kHz always-on clock (timer_32k_ck) 15*c66ec88fSEmmanuel Vadot - 0x02 - external clock (timer_ext_ck, OMAP2 only) 16*c66ec88fSEmmanuel Vadot 17*c66ec88fSEmmanuel VadotExample: 18*c66ec88fSEmmanuel Vadot pwm9: dmtimer-pwm@9 { 19*c66ec88fSEmmanuel Vadot compatible = "ti,omap-dmtimer-pwm"; 20*c66ec88fSEmmanuel Vadot ti,timers = <&timer9>; 21*c66ec88fSEmmanuel Vadot #pwm-cells = <3>; 22*c66ec88fSEmmanuel Vadot }; 23
