+/* GENERAL NOTES:
+ *
+ * BUGS:
+ * - There are pops (we can't delay in trigger function, cause midlevel
+ * often need to trigger down and then up very quickly).
+ * Any ideas?
+ * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
+ */
+
+/*
+ * ES1868 NOTES:
+ * - The chip has one half duplex pcm (with very limited full duplex support).
+ *
+ * - Duplex stereophonic sound is impossible.
+ * - Record and playback must share the same frequency rate.
+ *
+ * - The driver use dma2 for playback and dma1 for capture.
+ */
+
+/*
+ * ES1869 NOTES:
+ *
+ * - there are a first full duplex pcm and a second playback only pcm
+ * (incompatible with first pcm capture)
+ *
+ * - there is support for the capture volume and ESS Spatializer 3D effect.
+ *
+ * - contrarily to some pages in DS_1869.PDF the rates can be set
+ * independently.
+ *
+ * - Zoom Video is implemented by sharing the FM DAC, thus the user can
+ * have either FM playback or Video playback but not both simultaneously.
+ * The Video Playback Switch mixer control toggles this choice.
+ *
+ * BUGS:
+ *
+ * - There is a major trouble I noted:
+ *
+ * using both channel for playback stereo 16 bit samples at 44100 Hz
+ * the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
+ *
+ * The same happens using Audio1 for captureing.
+ *
+ * The Windows driver does not suffer of this (although it use Audio1
+ * only for captureing). I'm unable to discover why.
+ *
+ */
+
+/*
+ * ES1879 NOTES:
+ * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
+ * seems to be effected (speaker_test plays a lower frequency). Can't find
+ * anything in the datasheet to account for this, so a Video Playback Switch
+ * control has been included to allow ZV to be enabled only when necessary.
+ * Then again on at least one test system the 0x71 bit 6 enable bit is not
+ * needed for ZV, so maybe the datasheet is entirely wrong here.
