Andre Przywara a6325e3e69 dt-bindings: memory-controllers: Convert Calxeda DDR to json-schema
Convert the Calxeda DDR memory controller binding to DT schema format
using json-schema.
Although this technically covers the whole DRAM controller, the
intention to use it only for error reporting and mapping fault addresses
to DRAM chips.

title: Calxeda DDR memory controller binding
description: |
The Calxeda DDR memory controller is initialised and programmed by the
firmware, but an OS might want to read its registers for error reporting
purposes and to learn about the DRAM topology.
