11- resets : Must contain an entry for each entry in reset-names.
12  See ../reset/reset.txt for details.
13- reset-names : Must include the following entries:
14  - spi
15- dmas : Must contain an entry for each entry in clock-names.
16  See ../dma/dma.txt for details.
17- dma-names : Must include the following entries:
