All platforms that use the common clk infrastructure should select COMMON_CLK from platform code, and on all other platforms, it must not be enabled, so there is no point making the option visible to users, and when it is visible, we break randconfig builds.

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.
