[GIT PULL] ARM: OMAP: Audio support via omap-twl4030 and pwm support

[Peter Ujfalusi]

Hi Tony,

The content of this pull:

update for audio support via omap-twl4030 and pwm updates in board level:
http://www.spinics.net/lists/linux-omap/msg85085.html

and zoom-peripherals update to not request the TWL GPIO7:
http://www.spinics.net/lists/linux-omap/msg85187.html

All is on top of mainline v3.8-rc4 tag.

Regards,
Péter

Have you already pulled this one? I can not find the patches in linux-next.

Looks like this now adds some new section warnings:

WARNING: vmlinux.o(.text+0x34124): Section mismatch in reference from the function sdp3430_twl_gpio_setup() to the function .init.text:omap_twl4030_audio_init()
The function sdp3430_twl_gpio_setup() references
the function __init omap_twl4030_audio_init().
This is often because sdp3430_twl_gpio_setup lacks a __init 
annotation or the annotation of omap_twl4030_audio_init is wrong.

WARNING: vmlinux.o(.text+0x34b8c): Section mismatch in reference from the function zoom_twl_gpio_setup() to the function .init.text:omap_twl4030_audio_init()
The function zoom_twl_gpio_setup() references
the function __init omap_twl4030_audio_init().
This is often because zoom_twl_gpio_setup lacks a __init 
annotation or the annotation of omap_twl4030_audio_init is wrong.

These can be fixed with the following patch, but I suspect some
of these cannot be __init/__initdata if the driver reprobes.

Can you please check this? I'll hold on sendinf off
this branch until it's been checked and fixed properly.

Regards,

Tony

For some reason the CONFIG_DEBUG_SECTION_MISMATCH got disabled in my rolling
kernel config...

I think this is not the correct way. the *_twl_gpio_setup() is called from the
gpio-twl4030 driver's platform_driver probe function which if I'm not mistaken
is not __init.

I think we should remove the __init from the omap_twl4030_audio_init() in
twl-common.c
With this change I do not have section mismatch either.

Seeing platform data marked with __initdata makes me extremely nervous.
Are you _absolutely_ _sure_ that this data either:

(a) gets copied before use, or
(b) is not used after kernel init

?

Normally, platform data is passed via a pointer in struct device to
drivers, and drivers either store a pointer to it, or if the driver is
unbound/rebound, they can access it well after init time.

Certainly marking a function pointed to by platform data as __init looks
very very wrong.

Yes let's do that rather than start copying things around. I'll apply
the following fix to the omap-for-v3.9/twl branch.

No, and that's why I said "I suspect some of these cannot be
__init/__initdata" and asked Peter to verify it :)

Yes it's not worth adding any copying of it in the twl-common.c.

It show for me as well now that I have enabled the
CONFIG_DEBUG_SECTION_MISMATCH in my config.

My GCC is:
armv7a-hardfloat-linux-gnueabi-gcc (Gentoo 4.7.2 p1.3, pie-0.5.5) 4.7.2

Cool, thanks Tony. I will drop my patch and pick the one from omap-for-v3.9/twl.

Thanks,
Péter

Maybe update your build scripts to always just:
$ ARCH=arm CONFIG_DEBUG_SECTION_MISMATCH=y make ...
