-/***************************************************************************************************
-*
-* To understand what Alsa Drivers should be doing look at "Writing an Alsa Driver" by Takashi Iwai
-* available in the Alsa doc section on the website
-*
-* A few notes to make things clearer. The UDA1341 is hooked up to Serial port 4 on the SA1100.
-* We are using SSP mode to talk to the UDA1341. The UDA1341 bit & wordselect clocks are generated
-* by this UART. Unfortunately, the clock only runs if the transmit buffer has something in it.
-* So, if we are just recording, we feed the transmit DMA stream a bunch of 0x0000 so that the
-* transmit buffer is full and the clock keeps going. The zeroes come from FLUSH_BASE_PHYS which
-* is a mem loc that always decodes to 0's w/ no off chip access.
-*
-* Some alsa terminology:
-* frame => num_channels * sample_size e.g stereo 16 bit is 2 * 16 = 32 bytes
-* period => the least number of bytes that will generate an interrupt e.g. we have a 1024 byte
-* buffer and 4 periods in the runtime structure this means we'll get an int every 256
-* bytes or 4 times per buffer.
-* A number of the sizes are in frames rather than bytes, use frames_to_bytes and
-* bytes_to_frames to convert. The easiest way to tell the units is to look at the
-* type i.e. runtime-> buffer_size is in frames and its type is snd_pcm_uframes_t
-*
-* Notes about the pointer fxn:
-* The pointer fxn needs to return the offset into the dma buffer in frames.
-* Interrupts must be blocked before calling the dma_get_pos fxn to avoid race with interrupts.
-*
-* Notes about pause/resume
-* Implementing this would be complicated so it's skipped. The problem case is:
-* A full duplex connection is going, then play is paused. At this point you need to start xmitting
-* 0's to keep the record active which means you cant just freeze the dma and resume it later you'd
-* need to save off the dma info, and restore it properly on a resume. Yeach!
-*
-* Notes about transfer methods:
-* The async write calls fail. I probably need to implement something else to support them?
