============================ C-SKY Multi-processors Timer ============================ C-SKY multi-processors timer is designed for C-SKY SMP system and the regs is accessed by cpu co-processor 4 registers with mtcr/mfcr. - PTIM_CTLR "cr<0, 14>" Control reg to start reset timer. - PTIM_TSR "cr<1, 14>" Interrupt cleanup status reg. - PTIM_CCVR "cr<3, 14>" Current counter value reg. - PTIM_LVR "cr<6, 14>" Window value reg to trigger next event. ============================== timer node bindings definition ============================== Description: Describes SMP timer PROPERTIES - compatible Usage: required Value type: Definition: must be "csky,mptimer" - clocks Usage: required Value type: Definition: must be input clk node - interrupts Usage: required Value type: Definition: must be timer irq num defined by soc Examples: --------- timer: timer { compatible = "csky,mptimer"; clocks = <&dummy_apb_clk>; interrupts = <16>; interrupt-parent = <&intc>; };
