Signed-off-by: Albert Herranz <albert_herr...@yahoo.es>
---
v1 -> v2
- Document new bindings in Documentation/powerpc/dts-bindings.
Suggestion by Grant Likely.
- Use same form for model property and compatible properties on the root
node. Suggestion by Grant Likely.
- Drop the model property in the soc node. Suggestion by Grant Likely.
- Move interrupt-parent to the soc node instead of explicitly adding it to
each child node. Suggestion by Grant Likely.
- Declare all available memory and deal with the hole and fb area in the
platform code. Suggestion by Segher Boessenkool.
- Rename the "soc" node to "hollywood". Suggestion by Benjamin Herrenschmidt.
- Remove the usbgecko node from the device tree and autodetect it in
platform code. Suggestion by Segher Boessenkool.
- Don't use #cpus in cpus node. Suggestion by Segher Boessenkool.
- Remove clock-frequency property from the soc node.
Suggestion by Segher Boessenkool.
- Create a processor-interface node and place flipper-pic into it.
Suggestion by Segher Boessenkool.
- Remove #interrupt-cells from the hollywood node.
Suggestion by Segher Boessenkool.
- Remove the mini header pointer from the device tree and deal with it
in platform code. Suggestion by Segher Boessenkool.
- Add "usb-ohci" to the compatible property of ohci nodes.
Suggestion by Segher Boessenkool.
- Add "usb-ehci" to the compatible property of ehci nodes.
Suggestion by Segher Boessenkool.
- Don't use a different name if the unit address is different.
Suggestion by Benjamin Herrenschmidt.
- Don't use "nobats", do a workaround in mmu_mapin_ram instead.
Suggestion by Benjamin Herrenschmidt.
- Rename "mini" node to "ipc" and set it compatible with
"nintendo,hollywood-ipc".
- Massive cleanups. Suggestions by Segher Boessenkool.
- Comment out i2c over gpio bindings until a standard is agreed.
- Use a single gpio controller node. It's just one controller with two
"views".

+ This node represents the Nintendo Wii video game console.
+
+ Required properties:
+
+ - model : Should be "nintendo,wii"
+ - compatible : Should be "nintendo,wii"
+
+1) The "hollywood" node
+
+ This node represents the multi-function "Hollywood" chip, which packages
+ many of the devices found in the Nintendo Wii.
+
+ Required properties:
+
+ - compatible : Should be "nintendo,hollywood"
+
+1.a) The Video Interface (VI) node
+
+ Represents the interface between the graphics processor and a external
+ video encoder.
+
+ Required properties:
+
+ - compatible : should be "nintendo,hollywood-vi","nintendo,flipper-vi"
+ - reg : should contain the VI registers location and length
+ - interrupts : should contain the VI interrupt
+
+1.b) The Processor Interface (PI) node
+
+ Represents the data and control interface between the main processor
+ and graphics and audio processor.
+
+ Required properties:
+
+ - compatible : should be "nintendo,hollywood-pi","nintendo,flipper-pi"
+ - reg : should contain the PI registers location and length
+
+1.b.i) The "Flipper" interrupt controller node
+
+ Represents the "Flipper" interrupt controller within the "Hollywood" chip.
