Please think of a better name of course. We can figure out how to handle non-DT platforms if we need to. With clkdev we could probably handle it with some sort of lookup table search given a device name. Don't add that part until we have a user though. I assume simplefb is all DT platforms? Either way, it looks like what we really want here is a way to get every clk for a device and not look at the details. USB has a similar case, which I think Shawn Guo/Dong Aisheng was trying to add an OF based bulk clk_get() API called of_clk_bulk_get() for[1]. If this get all clks API works there too then we should use it. If it can be non-DT specific, even better.
