-Binding for Qualcomm Atheros AR7xxx/AR9xxx DDR controller
-
-The DDR controller of the AR7xxx and AR9xxx families provides an interface
-to flush the FIFO between various devices and the DDR. This is mainly used
-by the IRQ controller to flush the FIFO before running the interrupt handler
-of such devices.
-
-Required properties:
-
-- compatible: has to be "qca,<soc-type>-ddr-controller",
- "qca,[ar7100|ar7240]-ddr-controller" as fallback.
- On SoC with PCI support "qca,ar7100-ddr-controller" should be used as
- fallback, otherwise "qca,ar7240-ddr-controller" should be used.
-- reg: Base address and size of the controller's memory area
-- #qca,ddr-wb-channel-cells: Specifies the number of cells needed to encode
- the write buffer channel index, should be 1.
-
-Example:
-
- ddr_ctrl: memory-controller@18000000 {
- compatible = "qca,ar9132-ddr-controller",
- "qca,ar7240-ddr-controller";
- reg = <0x18000000 0x100>;
-
- #qca,ddr-wb-channel-cells = <1>;
- };
-
- ...
-
- interrupt-controller {
- ...
- qca,ddr-wb-channel-interrupts = <2>, <3>, <4>, <5>;
- qca,ddr-wb-channels = <&ddr_ctrl 3>, <&ddr_ctrl 2>,
- <&ddr_ctrl 0>, <&ddr_ctrl 1>;
- };

I applied forgetting you are maintaining the memory-controller
bindings. I can drop if you prefer. I see you've got a few more too.

No need, I don't expect dependencies and it is already late in the
cycle. Feel free to take all of the bindings patches.
Thanks!
Best regards,
Krzysztof
