The timer and ipi device are on the different address, and can not be handled by the sifive,clint dt-bindings. If we use the same compatible string for mswi and timer of the sg2042 clint like sifive,clint, the DT may be like this: mswi: interrupt-controller@94000000 { compatible = "sophgo,sg2042-clint", "thead,c900-clint"; interrupts-extended = <&cpu1intc 3>; reg = <0x94000000 0x00010000>; }; timer: timer@ac000000 { compatible = "sophgo,sg2042-clint", "thead,c900-clint"; interrupts-extended = <&cpu1intc 7>; reg = <0xac000000 0x00010000>; }; Since the address of mswi and timer are different, it is hard to merge them directly. So we need two DT nodes to handle both devices. If we use this DT for SBI, it will parse the mswi device in the timer initialization as the compatible string is the same, so will mswi. As they are different devices, this incorrect initialization will cause the system unusable. There is a more robust ACLINT spec. can handle this situation, but the spec. seems to be abandoned and will not be frozen in the predictable future. So it is not the time to add ACLINT spec in the kernel bindings. Instead, using vendor bindings is more acceptable. Add new vendor specific compatible strings to identify timer of sg2042 clint.
