The common clock framework is a single definition of struct
|
||
|
|
clk, useful across many platforms, as well as an
|
||
|
|
implementation of the clock API in include/linux/clk.h.
|
||
|
|
Architectures utilizing the common struct clk should select
|
||
|
|
this option.

|
Traverses the entire clock tree and disables any clocks that are
|
||
|
|
enabled in hardware but have not been enabled by any device drivers.
|
||
|
|
This saves power and keeps the software model of the clock in line
|
||
|
|
with reality.

|
|

|
If in doubt, say "N".
