This patch is OK for me but I would like to apply it myself on
mvebu/dt. Indeed Thomas Petazzoni pointed that I made a typo on the
peripheral clock label: nb_perih_clk instead of nb_periph_clk. I would
like to fix it and by applying this patch I will avoid a merge conflict
or worse a mismatch with the label name.
Wolfram, once you will be OK with the patch 1 and 3, I will apply the
patch 2.
Thanks,
Gregory
