- * Power management sequences
- * ==========================
- *
- * The following explains the PM handling of HDAC HDMI with its parent
- * device SKL and display power usage
- *
- * Probe
- * -----
- * In SKL probe,
- * 1. skl_probe_work() powers up the display (refcount++ -> 1)
- * 2. enumerates the codecs on the link
- * 3. powers down the display  (refcount-- -> 0)
- *
- * In HDAC HDMI probe,
- * 1. hdac_hdmi_dev_probe() powers up the display (refcount++ -> 1)
- * 2. probe the codec
- * 3. put the HDAC HDMI device to runtime suspend
- * 4. hdac_hdmi_runtime_suspend() powers down the display (refcount-- -> 0)
- *
- * Once children are runtime suspended, SKL device also goes to runtime
- * suspend
- *
- * HDMI Playback
- * -------------
- * Open HDMI device,
- * 1. skl_runtime_resume() invoked
- * 2. hdac_hdmi_runtime_resume() powers up the display (refcount++ -> 1)
- *
- * Close HDMI device,
- * 1. hdac_hdmi_runtime_suspend() powers down the display (refcount-- -> 0)
- * 2. skl_runtime_suspend() invoked
- *
- * S0/S3 Cycle with playback in progress
- * -------------------------------------
- * When the device is opened for playback, the device is runtime active
- * already and the display refcount is 1 as explained above.
- *
- * Entering to S3,
- * 1. hdmi_codec_prepare() invoke the runtime resume of codec which just
- *    increments the PM runtime usage count of the codec since the device
- *    is in use already
- * 2. skl_suspend() powers down the display (refcount-- -> 0)
- *
- * Wakeup from S3,
- * 1. skl_resume() powers up the display (refcount++ -> 1)
- * 2. hdmi_codec_complete() invokes the runtime suspend of codec which just
- *    decrements the PM runtime usage count of the codec since the device
- *    is in use already
- *
- * Once playback is stopped, the display refcount is set to 0 as explained
- * above in the HDMI playback sequence. The PM handlings are designed in
- * such way that to balance the refcount of display power when the codec
- * device put to S3 while playback is going on.
- *
- * S0/S3 Cycle without playback in progress
- * ----------------------------------------
- * Entering to S3,
- * 1. hdmi_codec_prepare() invoke the runtime resume of codec
- * 2. skl_runtime_resume() invoked
- * 3. hdac_hdmi_runtime_resume() powers up the display (refcount++ -> 1)
- * 4. skl_suspend() powers down the display (refcount-- -> 0)
- *
- * Wakeup from S3,
- * 1. skl_resume() powers up the display (refcount++ -> 1)
- * 2. hdmi_codec_complete() invokes the runtime suspend of codec
- * 3. hdac_hdmi_runtime_suspend() powers down the display (refcount-- -> 0)
- * 4. skl_runtime_suspend() invoked
