Hello,

This series brings initial support for memory interconnect to Tegra20,
Terga30 and Tegra124 SoCs. The interconnect provides are quite generic
and should be suitable for all Tegra SoCs, but currently upstream kernel
has EMC/MC drivers only for those three generations of Tegra SoCs.

For the start only display controllers are getting interconnect API
support, others could be supported later on. The display controllers
have the biggest demand for interconnect API right now because dynamic
memory frequency scaling can't be done safely without taking into account
bandwidth requirement from the displays.
