[PATCH 0/2] marzen-reference ethernet patches

[Laurent Pinchart]

Hello,

Here are two small patches that attemps to fix ethernet support for the
marzen-reference board. Unfortunately this doesn't seem to be enough, I still
can't get any meaningful interrupt from the smsc911x ethernet controller.

I'm probably not going to spend more time on this, it would be appreciated if
anyone could take over.

Laurent Pinchart (2):
  ARM: shmobile: marzen-reference: Reference the correct IRQ for
    ethernet
  ARM: shmobile: marzen-reference: Update lan device name in pinctrl
    maps

Thanks for these. I have also previously unsuccessfully tried  to
get ethernet working for marzen-reference. I'll try again basing
my work on these new patches that you have provided.

Thanks. I've tried to solve the issue for a couple of hours tonight, and ran 
into irqpin-related interrupt storms. Guennadi has posted a patch to fix the 
problem a while ago ("[PATCH 1/3] ARM: shmobile: irqpin: fix handling of 
spurious interrupts in DT case") but it got rejected. Fixing that might be a 
prerequisite to get ethernet working correctly.

Thanks. It sounds painful.
