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.

---help---
|
|
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".

---help---
|
|
Creates a directory hierchy in debugfs for visualizing the clk
|
|
tree structure. Each directory contains read-only members
|
|
that export information specific to that clk node: clk_rate,
|
|
clk_flags, clk_prepare_count, clk_enable_count &
|
|
clk_notifier_count.
