Hi,
it's finally working! :)
Great news! ;) I guess you now have all required features working with
latest mainline kernel ? Is there anything still missing ?
This is my entire diff: http://pastie.org/5674242 (note: it doesn't include
sound/soc/samsung/mini6410_wm9713.c file, which is a copy of the
smdk6410_wm9713.c file)
Here's the mini6410_wm9713.c file: http://pastie.org/5674322
This is what I'm getting from boot:
soc-audio soc-audio: ASoC machine SMDK WM9713 should use snd_soc_register_card()
soc-audio soc-audio: wm9713-hifi<-> samsung-ac97 mapping ok
ALSA device list:
#0: MINI6410
which is what I was expecting (at least that's what I get booting the
FriendlyARM kernel).
Sounds good.
I had to unmute everything because everything was muted by default,
but that really doesn't bother me.
The bad part is that, as Andrey told us, the filter hack is necessary.
If I remove it, I can't get any sound working.
Even further, if I try to run some amixer sset commands to unmute a
control, I get a few printfs with
"ac97: req addr = 12, rep addr = 00".
Also, there is one strange compile warning which I'm not able to
understand where is coming from:
WARNING: vmlinux.o(.data+0x6a78): Section mismatch in reference from
the variable smdk6410_b_pwr_5v_data to the (unknown reference)
.init.data:(unknown)
The variable smdk6410_b_pwr_5v_data references
the (unknown reference) __initdata (unknown)
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
I do know that it came right after adding the mini6410_wm9713.c to the
Makefile but that really shouldn't make it bug. Also, it has nothing
to do with SMDK, which
is what this warning is suggesting. I'm not using
smdk6410_b_pwr_5v_data in my mach-mini6410.c so...
This is an issue at the SMDK board file, don't need to worry about it.
I must have shown up when the kernel got linked again. The below patch
should fix that issue.
Sylwester, I can start sending you well-formated patches now or I can
wait for the filter hack to be fixed first, just say :)
I know I asked you previously for preparing patches so others don't
need to waste much time to enable all required features on those s3c64xx
reference boards. But now when there is the device tree support for
s3c64xx SoCs on the horizon [1], I'm not sure if we should be updating
the board files. Especially adding new static platform devices might be
not welcome.
@Kukjin: Do you think we can merge things like in this diff:
http://pastie.org/5674242, while device tree support is being worked on ?
Or should that be rather kept in private branches ?

Subject: [PATCH] ARM: S3C64XX: Fix section mismatch in smdk6410 board file
This patch corrects smdk6410_b_pwr_5v_consumers[] array attribute
and eliminates following compilation warning:
WARNING: arch/arm/mach-s3c64xx/built-in.o(.data+0x5704): Section mismatch
in reference from the variable smdk6410_b_pwr_5v_data to the (unknown

The variable smdk6410_b_pwr_5v_data references
the (unknown reference) __initdata (unknown)
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
