Subject: [PATCH] OPP: Provide old opp to config_clks on _set_opp
|
|
|
|
With the target opp, also pass the old opp to config_clks function.
|
|
This can be useful when a driver needs to take decision on what fequency
|
|
to set based on what is the current frequency without using a
|
|
clk_get_freq call.
|
|
Update the only user of custom config_clks (tegra30 devfreq driver) to
|
|
this new implementation.
