Please use string names instead of hard-coded integers.
interconnects = <&rsc_hlos MASTER_MDP0 &rsc_hlos SLAVE_EBI1>,
<&rsc_hlos MASTER_MDP1 &rsc_hlos SLAVE_EBI1>;

We are trying to be more descriptive and include both the source and the
destination like: "mdp0-mem", "mdp1-mem"

Otherwise looks good.
