I have reproduced this and first tried to break the loop at the top by
selecting CMA from DRM_TVE200 instead of depending on it:
drivers/dma/Kconfig:5:error: recursive dependency detected!
For a resolution refer to Documentation/kbuild/kconfig-language.txt

subsection "Kconfig recursive dependency limitations"
drivers/dma/Kconfig:387: symbol MX3_IPU depends on DMADEVICES
I've sent a patch [1] instead to make THERMAL selectable via a Kconfig
option.
