#include <dt-bindings/clock/imx6qdl-clock.h>
The i.MX SoCs have various power domain configurations routed into the PCIe IP. MX6SX is the only one which contains 2 domains and also uses power-domain-names. MX6QDL do not use any domains. All the rest uses one domain and does not use power-domain-names anymore. Document all those configurations in the DT binding document.
