optimize WSPLL work for iriver h100 and h300 series

2014-09-05T07:14:53+00:00

For Iriver h100 & h300 series we don't need always use WSPLL,
because in most cases WSPLL clock and SYSCLK has the same value,
and we have additional WSPLL errors to the output clock. Now that is fixed.

some optimization for iriver h100 and h300 series

2014-03-18T13:12:06+00:00

Turn on 4x oversampling inside UDA1380 codec.

This allow will move the quantization noise to the higher frequencies,
that slightly improve the final sound quality.

Add missing kernel.h includes (hopefully all of them).

Straighten out the mad twisted state of sound.c and related areas.

This is going right in since it's long overdue. If anything is goofed,
drop me a line or just tweak it yourself if you know what's wrong. :-)

Make HW/SW codec interface more uniform when emulating HW functionality
on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to-
DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX"
APIs are all in sound.c with none in DSP code any longer.

Reduce number of settings definitions needed by each codec by providing
defaults for common ones like balance, channels and SW tone controls.

Remove need for separate SIM code and tables and add virtual codec header
for hosted targets.

More minor const/static/include fixes.

Remove pcm_mute() which has been unused since r19308

2010-04-27T00:05:02+00:00

Remove audiohw_mute from header as well, and make this function static
to each driver (commented out when it was unused)

Update the uda1380 codec driver to allow it to be used without the WSPLL for playback and allow the use of a 256Fs clock signal directly at the SYSCLK input instead. This is required for the Meizus.

Create an udacodec interface (similar to ascodec and wmcoded) and adapt/implement it for the iriver h1xx/h3xx and the meizus.

Bring consistency to pcm implementation and samplerate handling. Less low-level duplication. A small test_sampr fix so it works on coldfire again.

Get rid of remaining audiohw_enable_output style codec setup and use pre/post split initialization. Move some SoC-specific code like i2s_reset out of the codec drivers. Helps to unify drivers and it was only ever used to enable. I cannot possibly test everything so report (I'll be on call ;) or fix problems if any crop up.
