Fabio Estevam - May 10, 2014, 3:47 p.m.
From: Fabio Estevam <fabio.estevam@freescale.com>

eukrea_mbimxsd51-baseboard.c and mach-cpuimx51sd.c can be replaced with their
devicetree equivalents: imx51-eukrea-mbimxsd51-baseboard.dts and 
imx51-eukrea-cpuimx51.dtsi respectively, so remove the board files.

This allows the conversion of mx51 to a devicetree-only platform.

This is not a dts patch, so I dropped 'dts' from patch prefix.

Applied both, thanks.

This patch just hit linux-next (in next-20140519) as "ARM: mx51: Remove
mach-cpuimx51sd board file".

It removed the Kconfig symbol MACH_EUKREA_MBIMXSD51_BASEBOARD. But it
left one reference to that symbol in sound/soc/fsl/Kconfig untouched,
see:

config SND_SOC_EUKREA_TLV320
	tristate "Eukrea TLV320"
	depends on MACH_EUKREA_MBIMX27_BASEBOARD \
		|| MACH_EUKREA_MBIMXSD25_BASEBOARD \
		|| MACH_EUKREA_MBIMXSD35_BASEBOARD \
		|| MACH_EUKREA_MBIMXSD51_BASEBOARD \
		|| (OF && ARM)
	depends on I2C
	select SND_SOC_TLV320AIC23_I2C
	select SND_SOC_IMX_AUDMUX
	select SND_SOC_IMX_SSI
	select SND_SOC_FSL_SSI
	select SND_SOC_IMX_PCM_DMA
	help
	  Enable I2S based access to the TLV320AIC23B codec attached
	  to the SSI interface

What should be done with that last reference?

Thanks for reporting.

MACH_EUKREA_MBIMXSD51_BASEBOARD should be removed from sound/soc/fsl/Kconfig.

Would you like to submit a patch?

Thanks for looking into this.

> Would you like to submit a patch?

Only if all you want for a commit explanation is something like "Remove
a select statement for MACH_EUKREA_MBIMXSD51_BASEBOARD. It's a NOP".
 
But I suppose it might be nice to add a few lines why removing config
MACH_EUKREA_MBIMXSD51_BASEBOARD didn't break the code (that is enabled
by setting SND_SOC_EUKREA_TLV320). And I wouldn't know how to write
those lines, because I have no idea how this all fits together. So I
actually prefer if someone else submitted that patch.

But I do hope you don't mind if I drop in a reminder if that patch takes
too long.

No problem. I can send a patch for this when 3.16-rc1 is out.

That's not needed anymore. Commit 7b8751abdd34 ("ASoC: fsl: Remove
dependencies of boards for SND_SOC_EUKREA_TLV320") landed in linux-next
about ten days ago and already removed this reference.
