The dmm@0 reg property above should be zero instead of 0x4e000000 now that
we're using ranges. Looks like I did not test with omapdrm loaded earlier,
updated patch below.

Subject: [PATCH] ARM: dts: Configure interconnect target module for dra7
dmm
We can now probe devices with device tree only configuration using
ti-sysc interconnect target module driver. Let's configure the
module, but keep the legacy "ti,hwmods" peroperty to avoid new boot
time warnings. The legacy property will be removed in later patches
together with the legacy platform data.
