OK, I gave this a quick try and it doesn't seem actually possible to
compile imx-ssi.c as a module without changing some code to separate ssi
and pcm parts which are actually mixed in imx-ssi.c.
So actually, selecting SND_IMX_SOC as a module produces snd-soc.imx.ko
which integrates the SSI driver + the PCM drivers.
So actually the 3 following configurations are possible (and tested on
my i.MX27 board) with the patch I sent for Kconfig :
- imx soc driver in kernel, board driver in kernel
- imx soc driver in kernel, board driver (snd-soc-eukrea-tlv320.ko) as a
- imx soc driver (snd-soc-imx.ko) and board driver
(snd-soc-eukrea-tlv320.ko) as 2 modules.
Also thanks for suggesting this Makefile edit, this allowed me to fix
sound support for my board when soc is compiled as a module ;-)
