| 16 | The common clock framework is a single definition of struct |
| 17 | clk, useful across many platforms, as well as an |
| 18 | implementation of the clock API in include/linux/clk.h. |
| 19 | Architectures utilizing the common struct clk should select |
| 20 | this option. |

| 29 | Traverses the entire clock tree and disables any clocks that are |
| 30 | enabled in hardware but have not been enabled by any device drivers. |
| 31 | This saves power and keeps the software model of the clock in line |
| 32 | with reality. |

| 41 | Creates a directory hierchy in debugfs for visualizing the clk |
| 42 | tree structure. Each directory contains read-only members |

| 45 | clk_notifier_count. |
