+ * 2. TW686X devices are capable of setting a few different DMA modes,
+ * including: scatter-gather, field and frame modes. However,
+ * under stress testings it has been found that the machine can
+ * freeze completely if DMA registers are programmed while streaming
+ * is active.
+ * This driver tries to access hardware registers as infrequently
+ * as possible by:
+ *   i.  allocating fixed DMA buffers and memcpy'ing into
+ *       vmalloc'ed buffers
+ *   ii. using a timer to mitigate the rate of DMA reset operations,
+ *       on DMA channels error.
