Hi,

 - G762 PWM fan controller on I2C bus: it requires G762 driver which
   is *currently sitting in hwmon maintainer tree* and will be available
   in 3.11. Jason, as a side note I have a short patch for available for
   ReadyNAS Duo v2 .dts file (the device also has a G762). I can hold
   it until rc cycle if you prefer.
Nope, post patches when you have them ready.  I am capable of holding
them until -rc1 drops ;-)
That's the one I sent yesterday (the patch tagged RESEND, i.e. w/o the
fixes for space issue in .dts file)

Jason, the tests were done against your for-next branch (with all the
fixes which accumulated in Linux tree from rc7). I will work directly
against Linus tree as soon as the rc- cycle for 3.11 starts. 
hmmm, my latest for-next (20130623) is based against v3.10-rc7, are you
using that?

Yes, but with just your tree I got some freezes during boot and applying
the additional commits available in Linux tree, this fixed the issue. I
did not spend much the time but I think this is related to
PJ4B_ERRATA_4742 which you do not have in your for-next branch:

    ARM: 7773/1: PJ4B: Add support for errata 4742
    
    This commit fixes the regression on Armada 370 (the kernal hang during
    boot) introduced by the commit: "ARM: 7691/1: mm: kill unused
    TLB_CAN_READ_FROM_L1_CACHE and use ALT_SMP instead".

I would just leave this out until we get the driver sorted.
ok, will do that in next versions.

My main question is for ISL12057 RTC chip: I guess it's just pointless to
push the .dts file for the RN102 w/o a working RTC clock?

Cheers,
