Hi Romain,

on a Radxa Rock when I try to remove the emac_rockchip module the
board locks up when calling clk_disable_unprepare(priv->refclk). The
tree is a net-next + your series, I don't know if I need some other

There is also the following build warning due to the emac dependency
on REGULATOR which in principle seems correct, but looking at other
drivers I wonder why they use the regulator APIs but don't have the
same dependency.

drivers/regulator/Kconfig:1:error: recursive dependency detected!
