Hi,

Add support for NETGEAR ReadyNAS Duo v2 (Hardware specs available
here: http://natisbad.org/NAS/). Almost everything is supported via
provided .dts. A board-readynas.c file is nonetheless required for
device not only converted to DT (Gbit controller).

FWIW, the most noticeable lack regarding hardware support is the fan
controller (GMT G762) for which nothing is currently available
upstream.

Changes since v1:
 - More specific compatible string in dts
 - Moved declaration to keep dts Makefile in alphabetical order
 - Removed unneeded mdelay() for USB power on
 - Switched to fixed regulator in .dts for USB power on

A previous version of the patch has been tested against 3.8.3 and the
one below against current arm tree (current head of rmk/for-next).

Hi Arnaud

Thats a nice description of the hardware. There is another device
using the same power supply controller, the USI Topkick. A few of the
maintainers have these, so there would be the possibility of
cooperating on a driver. It does not seem that complex a device. The
topkick also seems to do Wake-on-LAN using this controller. There was
a patch added recently which may allow this to work, depending on the
PHY.

Keeping with alphabetic ordering, it should be one place higher....

Again, should be a bit earlier.

Yes, you can guess.... Where ever you have inserted something, make
sure it follows the given ordering. The issue here is merge
conflicts. If we get another device contributed that is also added at
the end, we get conflicts. If merges happening in the middle, the
likelihood of a conflict is much smaller.

Now that the msleep() has gone, delay.h is probably not needed.  Maybe
also io.h is not needed any more with the regulator DT?

These are all minor issues. The code is good otherwise.

      Thanks

Does not come as a surprise. Netgear's 2.6.31.8 kernel contains a lot of
the following:
 
 This kernel which derived from kernel-2.6.31-topkick1281p2 used for
 both Netgear DUOv3 and NV+v4. It is based on kernel 2.6.31.8 and
 Marvell 5.1.3 patch. Specially the USB3.0 driver come from kernel
 2.6.39.

Note: everything in it is marked DUOv3 even though the device is branded
      Duo v2. Don't know why.

Damned, I saw TS followed by DOCKSTAR and thought the rule did not
apply. Will resend a v3 with corrected ordering ...

... and that one too. Good catch.
