Admittedly I think that the OMAP code could migrate some of these bits to a lazy-registration model, specifically the hwmod object instances, but that requires an awful lot of refactoring for a fairly large stack of platform code. This might be something to achieve in the future but for now we *need* initialisation to be fully static.
When we work on moving clocks to device tree, wouldn't you face the same problem? You will have to dynamically create most of the clocks in that case too.
From what I heard from Mike[1], Omap will not have most of the clocks
encoded in device tree.
Although my original preference was to have all the clocks represented in device tree and dynamically registered to clk framework, I've heard people including Grant incline to only have oscillator and leaf modules clocks in device tree. I somehow agree with that now, because having all the clocks in there will bloat device tree dramatically, considering there will be 3 clks, clk_gate, clk_divider and clk_mux backing one clock in general.
Assuming we would agree to have most SoC internal clocks registered from clock driver rather than device tree, I would like to hear about how we should have these clock registered from clock driver, static initialization or using register function?
