pinctrl-names and pinctrl-0 are usually at the top. However, since there is no 
hard rule (I've seen it mixed), I'm fine with it.

Acked-by: Jernej Skrabec <jernej.skrabec at gmail.com>

Since original DT node entry goes through netdev tree, this should be picked 
there or it can be dropped there and I pick both patches or I can pick patch 
for later kernel version.

Best regards,
Jernej
