2100 | * Power management sequences | |
2101 | * ========================== | |
2102 | * | |
2103 | * The following explains the PM handling of HDAC HDMI with its parent | |
2104 | * device SKL and display power usage | |
2105 | * | |
2106 | * Probe | |
2107 | * ----- | |
2108 | * In SKL probe, | |
2109 | * 1. skl_probe_work() powers up the display (refcount++ -> 1) | |
2110 | * 2. enumerates the codecs on the link | |
2111 | * 3. powers down the display (refcount-- -> 0) | |
2112 | * | |
2113 | * In HDAC HDMI probe, | |
2114 | * 1. hdac_hdmi_dev_probe() powers up the display (refcount++ -> 1) | |
2115 | * 2. probe the codec | |
2116 | * 3. put the HDAC HDMI device to runtime suspend | |
2117 | * 4. hdac_hdmi_runtime_suspend() powers down the display (refcount-- -> 0) | |
2118 | * | |
2119 | * Once children are runtime suspended, SKL device also goes to runtime | |
2120 | * suspend | |
2121 | * | |
2122 | * HDMI Playback | |
2123 | * ------------- | |
2124 | * Open HDMI device, | |
2125 | * 1. skl_runtime_resume() invoked | |
2126 | * 2. hdac_hdmi_runtime_resume() powers up the display (refcount++ -> 1) | |
2127 | * | |
2128 | * Close HDMI device, | |
2129 | * 1. hdac_hdmi_runtime_suspend() powers down the display (refcount-- -> 0) | |
2130 | * 2. skl_runtime_suspend() invoked | |
2131 | * | |
2132 | * S0/S3 Cycle with playback in progress | |
2133 | * ------------------------------------- | |
2134 | * When the device is opened for playback, the device is runtime active | |
2135 | * already and the display refcount is 1 as explained above. | |
2136 | * | |
2137 | * Entering to S3, | |
2138 | * 1. hdmi_codec_prepare() invoke the runtime resume of codec which just | |
2139 | * increments the PM runtime usage count of the codec since the device | |
2140 | * is in use already | |
2141 | * 2. skl_suspend() powers down the display (refcount-- -> 0) | |
2142 | * | |
2143 | * Wakeup from S3, | |
2144 | * 1. skl_resume() powers up the display (refcount++ -> 1) | |
2145 | * 2. hdmi_codec_complete() invokes the runtime suspend of codec which just | |
2146 | * decrements the PM runtime usage count of the codec since the device | |
2147 | * is in use already | |
2148 | * | |
2149 | * Once playback is stopped, the display refcount is set to 0 as explained | |
2150 | * above in the HDMI playback sequence. The PM handlings are designed in | |
2151 | * such way that to balance the refcount of display power when the codec | |
2152 | * device put to S3 while playback is going on. | |
2153 | * | |
2154 | * S0/S3 Cycle without playback in progress | |
2155 | * ---------------------------------------- | |
2156 | * Entering to S3, | |
2157 | * 1. hdmi_codec_prepare() invoke the runtime resume of codec | |
2158 | * 2. skl_runtime_resume() invoked | |
2159 | * 3. hdac_hdmi_runtime_resume() powers up the display (refcount++ -> 1) | |
2160 | * 4. skl_suspend() powers down the display (refcount-- -> 0) | |
2161 | * | |
2162 | * Wakeup from S3, | |
2163 | * 1. skl_resume() powers up the display (refcount++ -> 1) | |
2164 | * 2. hdmi_codec_complete() invokes the runtime suspend of codec | |
