37 * Locking: 36 * Locking:
38 * 37 *
39 * Each struct clk has a spinlock.
40 *
41 * To avoid AB-BA locking problems, locks must always be traversed from child
42 * clock to parent clock. For example, when enabling a clock, the clock's lock
43 * is taken, and then clk_enable is called on the parent, which take's the
44 * parent clock's lock. There is one exceptions to this ordering: When dumping
45 * the clock tree through debugfs. In this case, clk_lock_all is called,
46 * which attemps to iterate through the entire list of clocks and take every
47 * clock lock. If any call to spin_trylock fails, all locked clocks are
48 * unlocked, and the process is retried. When all the locks are held,
49 * the only clock operation that can be called is clk_get_rate_all_locked.
50 *
51 * Within a single clock, no clock operation can call another clock operation
52 * on itself, except for clk_get_rate_locked and clk_set_rate_locked. Any
53 * clock operation can call any other clock operation on any of it's possible
54 * parents.
55 *
56 * An additional mutex, clock_list_lock, is used to protect the list of all 38 * An additional mutex, clock_list_lock, is used to protect the list of all
57 * clocks. 39 * clocks.
58 * 40 *
59 * The clock operations must lock internally to protect against
