That's the one I sent yesterday (the patch tagged RESEND, i.e. w/o the
fixes for space issue in .dts file)

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".

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?
