[PATCH v6 08/15] ARM: tegra: Add EMC to Tegra124 device tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Mikko Perttunen <mperttunen@xxxxxxxxxx>

This adds a node for the EMC memory controller. It is always enabled, but only
provides read-only functionality without board-specific timing tables.

v5: Add a phandle to the CAR node that points to the EMC node
