/*
sa1100 provides its own variant of the clk API rather than using the generic COMMON_CLK API. This generally works, but it causes some link errors with drivers using the clk_set_rate, clk_get_parent, clk_set_parent or clk_round_rate functions when a platform lacks those interfaces. This adds trivial stub implementations for each of them, based on the behavior of the COMMON_CLK implementation: - set_rate() and set_parent() report success without doing anything - round_rate() returns the clk rate - get_parent() returns NULL. This adds the minimal bloat and should do the right thing for the simple clock hardware in this SoC.
