+/**
+ * DOC: LPE Audio integration for HDMI or DP playback
+ *
+ * Motivation:
+ * Atom platforms (e.g. valleyview and cherryTrail) integrates a DMA-based
+ * interface as an alternative to the traditional HDaudio path. While this
+ * mode is unrelated to the LPE aka SST audio engine, the documentation refers
+ * to this mode as LPE so we keep this notation for the sake of consistency.
+ *
+ * The interface is handled by a separate standalone driver maintained in the
+ * ALSA subsystem for simplicity. To minimize the interaction between the two
+ * subsystems, a bridge is setup between the hdmi-lpe-audio and i915:
+ * 1. Create a platform device to share MMIO/IRQ resources
+ * 2. Make the platform device child of i915 device for runtime PM.
+ * 3. Create IRQ chip to forward the LPE audio irqs.
+ * the hdmi-lpe-audio driver probes the lpe audio device and creates a new
+ * sound card
+ *
+ * Threats:
+ * Due to the restriction in Linux platform device model, user need manually
+ * uninstall the hdmi-lpe-audio driver before uninstalling i915 module,
+ * otherwise we might run into use-after-free issues after i915 removes the
+ * platform device: even though hdmi-lpe-audio driver is released, the modules
+ * is still in "installed" status.
+ *
+ * Implementation:
+ * The MMIO/REG platform resources are created according to the registers
+ * specification.
+ * When forwarding LPE audio irqs, the flow control handler selection depends
+ * on the platform, for example on valleyview handle_simple_irq is enough.

+ * PCM ring buffer handling
+ *
+ * The hardware provides a ring buffer with the fixed 4 buffer descriptors
+ * (BDs). The driver maps these 4 BDs onto the PCM ring buffer. The mapping
+ * moves at each period elapsed. The below illustrates how it works:
+ *
+ * At time=0
+ * PCM | 0 | 1 | 2 | 3 | 4 | 5 | .... |n-1|
+ * BD | 0 | 1 | 2 | 3 |
+ *
+ * At time=1 (period elapsed)
+ * PCM | 0 | 1 | 2 | 3 | 4 | 5 | .... |n-1|
+ * BD | 1 | 2 | 3 | 0 |
+ *
+ * At time=2 (second period elapsed)
+ * PCM | 0 | 1 | 2 | 3 | 4 | 5 | .... |n-1|
+ * BD | 2 | 3 | 0 | 1 |
+ *
+ * The bd_head field points to the index of the BD to be read. It's also the
+ * position to be filled at next. The pcm_head and the pcm_filled fields
+ * point to the indices of the current position and of the next position to
+ * be filled, respectively. For PCM buffer there are both _head and _filled
+ * because they may be difference when nperiods > 4. For example, in the
+ * example above at t=1, bd_head=1 and pcm_head=1 while pcm_filled=5:
+ *
+ * pcm_head (=1) --v v-- pcm_filled (=5)
+ * PCM | 0 | 1 | 2 | 3 | 4 | 5 | .... |n-1|
+ * BD | 1 | 2 | 3 | 0 |
+ * bd_head (=1) --^ ^-- next to fill (= bd_head)
+ *
+ * For nperiods < 4, the remaining BDs out of 4 are marked as invalid, so that
+ * the hardware skips those BDs in the loop.
+ *
+ * An exceptional setup is the case with nperiods=1. Since we have to update
+ * BDs after finishing one BD processing, we'd need at least two BDs, where
+ * both BDs point to the same content, the same address, the same size of the
+ * whole PCM buffer.
