Hello Sebastian,

This patch set fixes clk init order that went upside-down with
v3.14. I haven't really investigated what caused this, but I assume
it is related with DT node reordering by addresses.

The framework should be able to deal with unordered registration. I am not very familiar with the mvebu driver though, do you have a valid reason to require a specific order?

Anyway, with v3.14 for MVEBU SoCs, the clock gating driver gets
registered before core clocks driver. Unfortunately, we cannot
return -EPROBE_DEFER in drivers initialized by clk_of_init.

Why would you need to do so? After a quick inspection on the code, I see you may have problems on mvebu_clk_gating_setup() when getting the default parent clock name, but I believe you could solve it in an easier way by using of_clk_get_parent_name().

Cheers,

Emilio
