Documentation: dt-bindings: minimal documentation for MVEBU SDRAM controller
The suspend/resume code for Armada XP has to modify certain registers of the SDRAM controller. Therefore, we need to define a Device Tree binding for this hardware block.

Device Tree bindings for MVEBU SDRAM controllers
|
||||
|
||||
The Marvell EBU SoCs all have a SDRAM controller. The SDRAM controller
|
||||
differs from one SoC variant to another, but they also share a number
|
||||
of commonalities.
|
||||
|
||||
For now, this Device Tree binding documentation only documents the
|
||||
Armada XP SDRAM controller.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: for Armada XP, "marvell,armada-xp-sdram-controller"
|
||||
- reg: a resource specifier for the register space, which should
|
||||
include all SDRAM controller registers as per the datasheet.
|
||||
|
||||
Example:
|
||||
|
||||
sdramc@1400 {
|
||||
compatible = "marvell,armada-xp-sdram-controller";
|
||||
reg = <0x1400 0x500>;
|
||||
};
