In the devicetree patch you say: "Change the timer layout in the dtb to fit the format that needed by the SBI." That seems like a far more important thing to say in the binding patch, since that is where the ABI is set. You also provide two links to discussion on the mailing list for opensbi, but provide no context in the commit message here for why they're relevant. The 005738 one doesn't seem to be relevant at all? Could you please resubmit this with a better commit message that explains why the ABI here needs to change?

To make thead aclint timer more closer to the aclint spec, use two regs to represent the mtime and mtimecmp.
