How to get the 1080I50 and 1080P50 image from DSI

Regarding to the DSI output of our custom tx1 board, I have two problems:
How to modify the dts to get the 1080I50 and 1080P50 image from DSI.The timings of 1080I50 and 1080P50 should be according to CEA-861 timings.
Dose DSI of tx1 support to output the image which is interlaced format.

Do the Tegra X1 display supports interlaced format?such as PAL(576I)、NTSC(480I)、or 1080I-50?

No,

TX1 and TX2 does not support interlaced format in our BSP.
