Problem compiling soc - imx31 and wm8753

Problem compiling soc - imx31 and wm8753

[Marcelo Utikawa da Fonseca]

Hi!
I am new here and do not know if I am posting correctly, please 
understand! :-)
I knew about this list in the wolfsonmicro website and I hope someone 
can help me...

I am facing a problem while compiling the sound support for imx31ads board.
I got the kernel from wolfsonmicro using the following command:

git clone git://opensource.wolfsonmicro.com/linux-2.6-asoc linux-2.6-asoc

After this I just copy the arch/arm/configs/mx31ads_defconfig to .config 
and run:

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- menuconfig

I selected Alsa support, SoC, Support for i.MX CPU and Support for 
i.MX31 - WM8753.
After this I run:

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- zImage

and I receive this error message:

I did not change nothing, just configure and compile...
My gcc version is 4.1.2 from Freescale.
What can be wrong? Could be this version of gcc a problem?
I already tried to correct the missing include files but the other 
errors are still there after the corrections...

Thanks in advance,
Marcelo Utikawa da Fonseca

The i.MX31 support that is present in ASoC git depends on underlying
support for the CPU which is not present in any mainline tree (which is
why this code has not been contributed to mainline yet).

Probably the easiest thing to do is to start from the BSP provided by
Freescale - I believe that most versions of that contain the CPU audio
drivers already, probably including a version of the WM8731 driver.  It
should be much easier to merge that driver (by itself, just wm8731.c and
wm8731.h) into the Freescale BSP than to merge the i.MX31 support into
the standard kernel.

The i.MX31 Freescale's BSP does not have asoc support, just an interface 
for MC13783 (a Power Management IC from Freescale with integrated audio 
interface).
The wolfsonmicro's tree is the only one that have support to asoc but it 
does not compiles using the mentioned steps.
Am I missing something or may be these drivers broken?

As I say, the drivers rely on code in the Freescale BSP; you may not
have the lastest Freescale BSP.  There is some code here:

	git://opensource.wolfsonmicro.com/linux-2.6-audioplus imx31

but note that this uses ASoC v2 so will definitely require some porting
of the WM8731 driver unless the copy there is already up to date.  That
tree is entirely focused on supporting the WM835x (an audio+PMIC device
comprable to the Atlas which is shipped by default) with the i.MX31ADS.

I'd also like to add that this was only a API/build testing driver. I
never actually had any real wm8753 + i.MX31 to hardware test against. I
just wanted to confirm the API fitted well here and I could build some
code.

I would do as Mark suggested and use the Freescale BSP. Easiest option.

Alternatively, if you have some time - have a look at mainline i.MX31
support and port the SDMA and SSI drivers from the Wolfson tree to it.
Not too much work for audio but you will also need to port other
required subsystems from the ancient kernel version in the Freescale BSP
to your current kernel which *will* eat into your project time.
