clk: respect the clock dependencies in of_clk_init
Until now the clock providers were initialized in the order found in the device tree. This led to have the dependencies between the clocks not respected: children clocks could be initialized before their parent clocks. Instead of forcing each platform to manage its own initialization order, this patch adds this work inside the framework itself. Using the data of the device tree the of_clk_init function now delayed the initialization of a clock provider if its parent provider was not ready yet. The strict dependency check (all parents of a given clk must be initialized) was added by Boris BREZILLON Signed-off-by:Gregory CLEMENT <gregory.clement@free-electrons.com> Signed-off-by:
