So I compared all the reg and interrupts properties against the T113
manual, they match, as far as they are described there. The undocumented
rest matches what we already have in other SoCs.

I noticed two things, though, mentioned inline below:

The clocks and the two mixers are not children of a bus node anymore,
IIUC correctly this was to manage the SRAM control. Is that now handled
differently, or does the D1 generation not require this anymore?

This is the same interrupt number as for the DSI controller above. Is
that correct, and can the drivers handle that?
