[PATCHv1] arm: armada: Add .dts file for Netgear ReadyNAS 102

[arno@natisbad.org (Arnaud Ebalard)]

All hardware parts of the (Armada 370 based) NETGEAR ReadyNAS 102 are
supported by mainline kernel (USB 3.0 rear ports, USB 2.0 front port,
Gigabit controller and PHY, serial port, leds, buttons, SATA ports,
G762 fan controller) except for:

 - the Intersil ISL12057 I2C RTC Chip,
 - the Armada NAND controller.

Support for both of those is currently work in progress and does not
prevent boot.

Hi Jason and Andrew,

As requested

 - this version is tested against current head of linus tree (+ I2C
   fixes for a race condition; for details, see message #94 of
   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=622325).
 - nand layout entry and ISL12057 entry have been removed until support
   is available in mainline kernel for eahc of those
 - clock, gpio led and keys have been made siblings of soc, memory and
   chosen (reported by Sebastian).

Is it still acceptable for current merge window or am I too late?

Cheers,

a+
