From: Inochi Amaoto <inochiama@xxxxxxxxxxx> The clint of Sophgo sg2042 is incompatible with the standard sifive clint, as the timer and ipi device on the different address, and can not be handled by the sifive,clint DT. In addition, the timers of sg2042 are mapped by per cluster, which is hard to merge with its ipi device. To avoid conficts caused by using the same clint compatible string when this device is parsed by SBI, add a new vendor specific compatible string to identify the timer of sg2042 soc.
