The patch is not that big and splitting it into several addons does not bring benefits. You still add new DTSI - either in one or two patches, there is going to be the same amount of code to review. One still has to review everything. It would be different if DTSI was already applied - then incremental updates make sense. Another reason for splitting is for different topics, when doing multiple separate actions, like fix + add, change + add. Best regards, Krzysztof
