sbi_set_timer() seems have no effect and do not trigger timer interrupt.

OpenSBI v1.2 is used from GitHub binary release (fw_dynamic.bin) with u-boot (mangopi_mq_pro_defconfig).

Not an OpenSBI issue. The problem is missing CLINT entry in FDT that I used (https://github.com/smaeul/u-boot/tree/d1-wip). SBI timer become functional after manually adding CLINT FDT definition.
