[WL1271 DC supprot on OMAP3EVM 4/5] ARM: Added ALSA audio support for WL1271 DC over the PCM interface (OMAP37XX)

[csanjay]

From: Sanjay Kumar Champati <csanjay@mistralsolutions.com>

* Add "wl1271bt.c" & "wl1271bt.h" in the PS kernel to support PCM interface for OMAP37XX
* Modified "Makefile" file to compile "wl1271bt.c" & "wl1271bt.h" files
* Modified "omap3evm.c" file to support Audio codec for WL1271 DC

[sp] I am not conversant with McBSP configuration, but isn't there
     a better way than directly manipulating on DEVCONF0?

     How is it done for other devices using McBSP? e.g. default
     audio on omap3evm.

Cannot pollute tty_io.c with omap-evm platform specific things

tty_io.c is a file part of generic tty-layer stack we cannot have
any platform specific things there.

bt_init_power
tty_setbt_power

All are one time configuration don't see why it needs
to be done with ioctl interface.
Can be done in board file itself.

Cannot pollute tty_io.c with omap-evm platform specific things

tty_io.c is a file part of generic tty-layer stack we cannot have
any platform specific things there.

bt_init_power
tty_setbt_power

All are one time configuration don't see why it needs
to be done with ioctl interface.
Can be done in board file itself.

     You cannot change the generic driver for custom implementation.

[sp] Can you describe how to use the MMC2 on omap3evm?
     Also, the name of the files modified is already part of the
     patch syntax. You don't need to mention them in the
     description here.

[sp] What is/will be the behavior on the boards where MMC2 isn't
     available on the board?

     I haven't verified, but this hunk also tells me that you haven't
     updated your development tree for long.

[sp] part of my question is: Why do you need to modify the
     generic sdio implementation to export these functions?

     You cannot make "custom" modifications here. See similar
     comment in other patch as well.
