I am still getting this failure.

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:5:	symbol DMADEVICES is selected by CRYPTO_DEV_SP_CCP
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/crypto/ccp/Kconfig:8:	symbol CRYPTO_DEV_SP_CCP depends on CRYPTO
For a resolution refer to Documentation/kbuild/kconfig-language.txt

fs/Kconfig:139:	symbol TMPFS is selected by DRM_ETNAVIV

drivers/gpu/drm/etnaviv/Kconfig:2:	symbol DRM_ETNAVIV depends on THERMAL

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.
