Subject: [PATCH v2 0/2] memory: tegra: Add Tegra264 support

From: Thierry Reding <treding@...dia.com>

This set of patches extends the DT bindings for the memory controller
and external memory controller for Tegra264 and add the necessary DT
headers with memory client and stream ID definitions.

The driver changes in patch 4 are mostly an extension of existing code
and the bulk consists of the memory client table for the new chip as
well as the bandwidth manager calculations.

Changes in v2:
- squash DT bindings patches into a single patch
- address review comments for bindings
- add Acked-by on patch 2
