struct_clk_notifier_data – rate data to pass to the notifier callback
Synopsis
struct clk_notifier_data {
struct clk *clk;
unsigned long old_rate;
unsigned long new_rate;
};Members
clk
- struct clk * being changed
old_rate
- previous rate of this clk
new_rate
- new rate of this clk
Description
For a pre-notifier, old_rate is the clk’s rate before this rate change, and new_rate is what the rate will be in the future. For a post-notifier, old_rate and new_rate are both set to the clk’s current rate (this was done to optimize the implementation).
