Hi Jiada

Thank you for your patch

This patch adds dma request number for busif0 ~ busif7 to be used by GEN3 series. GEN2 continues to use rxu/txu for busif data transfer.

In theory, I think DT side patch should be posted/applied if driver side patch was accepted. And, Gen3 side DT doesn't need "rxu/txu" I think.

OK, I will separate DT and driver side change, will remove DT change in next version.
