trace: power: add trace_clock_set_parent Adds a new trace event to be called from clk_set_parent. Some cpufreq drivers, including Tegra, reparent the cpu clock to a slower clock while the main pll is relocking, tracing clk_set_parent allows traces to show how for long the cpu is running slower. Uses a separate TRACE_EVENT instead of the clock event class to allow the event to contain string names for the child and the parent. Signed-off-by: Colin Cross <ccross@android.com>
