TIMER0, TIMER1, TIMER2, Timer3, TIMER4 and TIMER5 are in the CPU subsystem, using timer ch0 ~ ch5 respectively. The timer clock is 24MHz OSC. This series are found on RK3368 SoC, verified on rk3368 evb board.

More consideration for the future. Although the "rk3288-timer" is working for 3368, agreed to add the 'rk3368-timer' for the rk3368-spec timer in the future. > >> + reg = <0x0 0xff810000 0x0 0x20>; >> + interrupts = <GIC_SPI 66 IRQ_TYPE_LEVEL_HIGH>; >> + }; >> + >> xin24m: oscillator { >> compatible = "fixed-clock"; >> clock-frequency = <24000000>; > > > > > -- > Thanks, > Caesar -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 4+ messages in thread
