Hello,

The aim of this series is to move the plat-omap/mcbsp.c driver out to sound/soc/omap/ By doing this we can combine the two levels of McBSP driver stack into a single one. Formally we had omap-mcbsp.[1-X] drivers (plat-omap/mcbsp.c), and omap-mcbsp-dai.[0-(X-1) drivers (sound/soc/omap/omap-mcbsp.c). We had global, shared structures, variables, pointers. The API between the two driver was a set of exported function calls where one of the parameter was the McBSP port id.

With this series we will have one driver for McBSP (omap-mcbsp.[1-X]) which is basically the ASoC dai driver. All exported/shared global structures are gone since we can use driver data for all ports in this way.

With the code in one place we can do further clean up in the McBSP driver, and adding new features will be much easier in the future. Also the DT support for McBSP will be significantly easier if we have one set of driver.

McBSP is only used by audio, there are no known other users of the OMAP McBSP (well, Nokia n700 has the WLAN connected through McBSP but we do not have driver for that anyway).

The series was created against Takashi's topic/asoc branch. I have tested it on Beagle xM, and compile tested it for OMAP1, OMAP2, and OMAP4 as well.

I'm going to do more work on the cleanup, and the plan is to merge the two files into one (mcbsp.c -> omap-mcbsp.c) eventually.

Comments, testers are welcome...

CC-ing Samuel as well since he is the original author of the plat-omap/mcbsp.c driver.
