[PATCH RFC v2 5/6] ARM: add Armada 1500 and Sony NSZ-GS7 device tree files

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

 




This adds very basic device tree files for the Marvell Armada 1500 SoC
(88DE3100) and the Sony NSZ-GS7 GoogleTV board. Currently, SoC only has
nodes for cpus, some clocks, l2 cache controller, local timer, apb timers,
uart, and interrupt controllers. The Sony NSZ-GS7 is a GoogleTV consumer
device comprising the Armada 1500 SoC above.

Changelog:
v1->v2:
- add binding documentation (Reported by Jason Cooper)
- change l2cc from aurora to tauros3 (Reported by Thomas Petazzoni)
- add copyright reference
- adapt compatibles to mach-berlin instead of mach-mvebu

+Marvell Berlin (88DE3xxx) family SoCs Device Tree Bindings
+---------------------------------------------------------------
+
+Boards with a SoC of the Marvell Berlin (88DE3xxx) family, e.g. Armada 1500
+shall have the following properties:
+
+* Required root node properties:
+compatible: must contain "marvell,berlin"
+
+In addition, the above compatible shall be extended with the specific
+SoC used, i.e.
+    "marvell,88de3100"	for Marvell 88DE3100 (Armada 1500),
+    "marvell,88de3010"	for Marvell 88DE3010 (Armada 1000),
+    "marvell,88de3005"	for Marvell 88DE3005 (Armada 1500-mini)
+
+* Example:
+
+/ {
+	model = "Sony NSZ-GS7";
+	compatible = "marvell,88de3100", "marvell,berlin";
+
+	...
+}
