+ * This will help the user space to load the device-specific Use Case Manager
+ * (UCM) configurations for the card.
+ *
+ * Possible card long names may be:
+ * DellInc.-XPS139343-01-0310JH
+ * ASUSTeKCOMPUTERINC.-T100TA-1.0-T100TA
+ * Circuitco-MinnowboardMaxD0PLATFORM-D0-MinnowBoardMAX
+ *
+ * This function also supports flavoring the card longname to provide
+ * the extra differentiation, like "vendor-product-version-board-flavor".
+ *
+ * We only keep number and alphabet characters and a few separator characters
+ * in the card long name since UCM in the user space uses the card long names
+ * as card configuration directory names and AudoConf cannot support special
+ * charactors like SPACE.

+ * 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.
