Signed-off-by: Krzysztof Kozlowski Reviewed-by: Ulf Hansson Acked-by: Stephen Boyd Reviewed-by: Rob Herring --- Changes since v2: 1. Keep description of consumers in power-domain.txt, 2. Rename power_domain.txt to power-domain.txt, 3. Indent example with four spaces (more readable). Changes since v1: 1. Select all nodes for consumers, 2. Remove from consumers duplicated properties with dt-schema, 3. Fix power domain pattern, 4. Remove unneeded types.
