 /*
  * Locking:
  *
- * Each struct clk has a spinlock.
- *
- * To avoid AB-BA locking problems, locks must always be traversed from child
- * clock to parent clock.  For example, when enabling a clock, the clock's lock
- * is taken, and then clk_enable is called on the parent, which take's the
- * parent clock's lock.  There is one exceptions to this ordering: When dumping
- * the clock tree through debugfs.  In this case, clk_lock_all is called,
- * which attemps to iterate through the entire list of clocks and take every
- * clock lock.  If any call to spin_trylock fails, all locked clocks are
- * unlocked, and the process is retried.  When all the locks are held,
- * the only clock operation that can be called is clk_get_rate_all_locked.
- *
- * Within a single clock, no clock operation can call another clock operation
- * on itself, except for clk_get_rate_locked and clk_set_rate_locked.  Any
- * clock operation can call any other clock operation on any of it's possible
- * parents.
- *
  * An additional mutex, clock_list_lock, is used to protect the list of all
  * clocks.
  *
- * The clock operations must lock internally to protect against
- * read-modify-write on registers that are shared by multiple clocks
