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