From 66cb6e9d79695f831efe96227a5b5d1064872e6a Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Sun, 22 Dec 2019 12:39:16 +0100 Subject: [PATCH 1/4] dt-bindings: memory-controller: Convert Tegra124 EMC to json-schema Convert the device tree bindings for the Tegra124 EMC controller to the DT schema format using json-schema. While at it, clean up the binding a little bit by removing any mention of how RAM code and clock frequency are represented in unit-addresses (which they aren't) and by adding the EMC clock without which the EMC controller can't change the frequency at which the external memory is clocked. While this is technically an ABI break (the clock was not required before), this should be fine because there isn't much that the EMC driver can do without access to the EMC clock.

4/4] dt-bindings: memory: Add Tegra186 memory subsystem The NVIDIA Tegra186 SoC contains a memory subsystem composed of the memory controller and the external memory controller. The memory controller provides interfaces for the memory clients to access the memory. Accesses can be either bounced through the SMMU for IOVA translation or directly to the EMC. The bulk of the programming of the external memory controller happens through interfaces exposed by the BPMP. Describe this relationship by adding a phandle reference to the BPMP to the EMC node.
