The original bindings in TXT were not complete, so add during conversion properties already used in DTS and/or in the driver: reg-names, dmas, interconnects, operating points and power-domains. Signed-off-by: Krzysztof Kozlowski --- Changes since v1: 1. Correct $ref path and remove interconnect minItems (Kuldeep). 2. Remove child tpm device from example. 3.
