change mipi-csi-2's configuration

we use tc358748xbg to do parallel---->csi-2 transform,now the toshiba’s FAE give me a suggestion: chagne some csi-2’s parameters.

CSI speed= 350Mbps,LPTX = 68.57ns,THS_prepare = 68.57ns,THS_prepare + THS_zero = 282.86ns;

can I modify it just at device-tree?

Those setting is for tc358748xbg not for tegra. You should consult with they driver to modify it.
