dscr nodes are missing and should be included
[SL] I don't have much idea about dcsr nodes structure and their respective testing, also couldn't find then in T4 device tree files. I have added initial device trees. Dcsr may be added later as updation. What do you say?

there is no IRQ for RTC on the board.
[SL] will remove it.
