73  * intel_wakeref_get: Acquire the wakeref
74  * @wf: the wakeref
76  * Acquire a hold on the wakeref. The first user to do so, will acquire
77  * the runtime pm wakeref and then call the @fn underneath the wakeref
80  * Note that @fn is allowed to fail, in which case the runtime-pm wakeref
83  * Returns: 0 if the wakeref was acquired successfully, or a negative error
97  * __intel_wakeref_get: Acquire the wakeref, again
98  * @wf: the wakeref
100  * Increment the wakeref counter, only valid if it is already held by
113  * intel_wakeref_get_if_in_use: Acquire the wakeref
114  * @wf: the wakeref
116  * Acquire a hold on the wakeref, but only if the wakeref is already
119  * Returns: true if the wakeref was acquired, false otherwise.
128  * intel_wakeref_put_flags: Release the wakeref
129  * @wf: the wakeref
132  * Release our hold on the wakeref. When there are no more users,
133  * the runtime pm wakeref will be released after the @fn callback is called
134  * underneath the wakeref mutex.
136  * Note that @fn is allowed to fail, in which case the runtime-pm wakeref
139  * Returns: 0 if the wakeref was released successfully, or a negative error
165  * intel_wakeref_lock: Lock the wakeref (mutex)
166  * @wf: the wakeref
168  * Locks the wakeref to prevent it being acquired or released. New users
169  * can still adjust the counter, but the wakeref itself (and callback)
180  * intel_wakeref_unlock: Unlock the wakeref
181  * @wf: the wakeref
194  * @wf: the wakeref
208  * intel_wakeref_is_active: Query whether the wakeref is currently held
209  * @wf: the wakeref
211  * Returns: true if the wakeref is currently held.

221  * @wf: the wakeref
232  * intel_wakeref_wait_for_idle: Wait until the wakeref is idle
233  * @wf: the wakeref
235  * Wait for the earlier asynchronous release of the wakeref. Note
237  * when you have control over the wakeref and trust no one else is acquiring
