Re: [PATCH] clk: Propagate clk_set_rate() if CLK_SET_PARENT_RATE present

Sometimes clocks provided to a consumer might not have .set_rate operation (like gate or mux clocks), but have CLK_SET_PARENT_RATE flag set. In that case it's usually possible to find a parent up the tree which is capable of setting the rate (div, pll, etc). Implement a simple lookup procedure for such cases, to traverse the clock tree until .set_rate capable parent is found, and use that parent to actually change the rate. The search will stop once the first .set_rate capable clock is found, which is usually enough to handle most cases.

Applied to u-boot/next, thanks!
