Subject[PATCH v4 7/9] ARM: add Armada 1500 and Sony NSZ-GS7 device tree files
Date
This adds very basic device tree files for the Marvell Armada 1500 SoC
(Berlin BG2) 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:
v3->v4:
- rename dts/dtsi to vendor,name.dts[i] (Suggested by Kumar Gala)
v2->v3:
- none
v1->v2:
- add "arm,pl310-cache" compatible to l2cc (Suggested by Mark Rutland)
- replace 88DE3xxx numbering with SoC variant name
(Requested by Jisheng Zhang)
RCFv2->v1:
- switch to (soon to be) correct "marvell,pj4b" cpu compatible
- reference fixed-clock for uarts instead of hard-coded clock-frequency
- disable timers except two for clksrc and clkevt
RFCv1->RFCv2:
- 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 SoC Family Device Tree Bindings
+---------------------------------------------------------------
+
+Boards with a SoC of the Marvell Berlin 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 and board used. Currently known SoC compatibles are:
+ "marvell,berlin2" for Marvell Armada 1500 (BG2, 88DE3100),
+ "marvell,berlin2cd" for Marvell Armada 1500-mini (BG2CD, 88DE3005)
+ "marvell,berlin2ct" for Marvell Armada ? (BG2CT, 88DE????)
+ "marvell,berlin3" for Marvell Armada ? (BG3, 88DE????)
+
+* Example:
+
+/ {
+ model = "Sony NSZ-GS7";
+ compatible = "sony,nsz-gs7", "marvell,berlin2", "marvell,berlin";
+
+ ...
+}
