The plat-samsung/s3c24??.h headers contain function declarations that are
mostly private to the relevant SoCs.
This patchset follows the work started by Kukjin Kim for newer Samsung-SoCs
and moves them from a global space to their SoC directories as common.h .
The the only non-mach user of these files is plat-s3c24xx/cpu.c . It seemes
to have been built to generalize the init of S3C24XX-SoCs, but in reality
its savings are rather low and introduce ifdef-voodoo to distinguish
between S3C2412 and S3C2416.
Therefore the series introduces common.c files for these SoCs, that now
contain the SoC-specific cpu-init - the relevant parts of the cpu.c code.
cpu.c is completely removed at the end of the series.
The number of lines add + deleted is mostly equal and the positive diffstat
results from the added GPL headers to the common.c files for the most part.
Another sign of low savings in the cpu.c abstraction.
As always, each patch is compile-tested individually and correctnes of the
move was tested on s3c2416 hardware - so hopefully I did not break any other
of the touched SoCs.
As with the newer SoCs more common code can move into the common.c files
later on.
The series is based on the linux-samsung/for-next branch of 2012-01-02,
as it needs the restart patches, that create the common.h for some SoCs.

clk_msysclk is not needed outside of s3c2443-clock.c.
Removing the extern declaration will prevent conflicts with the
s3c2412 clk_msysclk in the following cleanups.

plat-samsung/clock.h currently keeps all the SoC specific clock
declarations except the ones for S3C2443/S3C2416 which were kept in
s3c2443.h.
This patch moves them out of s3c2443.h to get rid of the header
completely later on.

* [PATCH 2/8] S3C24XX: move common S3C2443 clock definitions to clock.h
@ 2012-01-06 23:24 ` Heiko Stübner

From: Heiko Stübner @ 2012-01-06 23:24 UTC (permalink / raw)
To: linux-arm-kernel
plat-samsung/clock.h currently keeps all the SoC specific clock
declarations except the ones for S3C2443/S3C2416 which were kept in
s3c2443.h.
This patch moves them out of s3c2443.h to get rid of the header
completely later on.

* [PATCH 4/8] S3C2416: move io-init to SoC specific files

Introduce common.h/common.c to replace calls to s3c24xx_init_io
and make the s3c2416.h header obsolete.
This also removes a cpu-specific ifdef in the common init function.

* [PATCH 4/8] S3C2416: move io-init to SoC specific files
@ 2012-01-06 23:26 ` Heiko Stübner
0 siblings, 0 replies; 22+ messages in thread
From: Heiko Stübner @ 2012-01-06 23:26 UTC (permalink / raw)
To: linux-arm-kernel
Introduce common.h/common.c to replace calls to s3c24xx_init_io
and make the s3c2416.h header obsolete.
This also removes a cpu-specific ifdef in the common init function.

* [PATCH 6/8] S3C2440: move io-init to SoC specific files
@ 2012-01-06 23:27 ` Heiko Stübner
0 siblings, 0 replies; 22+ messages in thread
From: Heiko Stübner @ 2012-01-06 23:27 UTC (permalink / raw)
To: linux-arm-kernel
Introduce common.c to replace calls to s3c24xx_init_io
and make the s3c244x.h header obsolete.

* [PATCH 7/8] S3C2412: move io-init to SoC specific files
2012-01-06 23:22 ` Heiko Stübner
@ 2012-01-06 23:28 ` Heiko Stübner

From: Heiko Stübner @ 2012-01-06 23:28 UTC (permalink / raw)
To: Kukjin Kim; +Cc: 'Ben Dooks', linux-arm-kernel, linux-samsung-soc
Introduce common.c to replace calls to s3c24xx_init_io
and make the s3c2412.h header obsolete.

* [PATCH 7/8] S3C2412: move io-init to SoC specific files
@ 2012-01-06 23:28 ` Heiko Stübner
0 siblings, 0 replies; 22+ messages in thread
From: Heiko Stübner @ 2012-01-06 23:28 UTC (permalink / raw)
To: linux-arm-kernel
Introduce common.c to replace calls to s3c24xx_init_io
and make the s3c2412.h header obsolete.

* [PATCH 8/8] S3C2410: move io-init to SoC specific files
2012-01-06 23:22 ` Heiko Stübner

From: Heiko Stübner @ 2012-01-06 23:28 UTC (permalink / raw)
To: Kukjin Kim; +Cc: 'Ben Dooks', linux-arm-kernel, linux-samsung-soc
Introduce common.c to replace calls to s3c24xx_init_io
and make the s3c2410.h header obsolete.
This also removes unnecessary references to s3c2410.h that were
still present in s3c2440 and s3c2443.

* [PATCH 8/8] S3C2410: move io-init to SoC specific files
@ 2012-01-06 23:28 ` Heiko Stübner
0 siblings, 0 replies; 22+ messages in thread
From: Heiko Stübner @ 2012-01-06 23:28 UTC (permalink / raw)
To: linux-arm-kernel
Introduce common.c to replace calls to s3c24xx_init_io
and make the s3c2410.h header obsolete.
This also removes unnecessary references to s3c2410.h that were
still present in s3c2440 and s3c2443.

Hi Heiko,
This approach looks good to me but since I was thinking we need to merge
various mach-s3c24{1,4}{0,2,6,0,3} directories to just one mach-s3c24xx
directory without plat-s3c24xx which can split into plat-samsung for all of
Samsung stuff and into mach-s3c24xx only for s3c24xx stuff, I didn't create
common.[ch] in each mach-s3c24xx directories. But now this could be good to
us...I think, we can make better output together about that. Let me back on
this after this merge window.
Thanks.
Best regards,
Kgene.

Hi Heiko,
This approach looks good to me but since I was thinking we need to merge
various mach-s3c24{1,4}{0,2,6,0,3} directories to just one mach-s3c24xx
directory without plat-s3c24xx which can split into plat-samsung for all of
Samsung stuff and into mach-s3c24xx only for s3c24xx stuff, I didn't create
common.[ch] in each mach-s3c24xx directories. But now this could be good to
us...I think, we can make better output together about that. Let me back on
this after this merge window.
Thanks.
Best regards,
Kgene.

To: Kukjin Kim; +Cc: 'Ben Dooks', linux-arm-kernel, linux-samsung-soc
Move s3c2443 specific code from s3c24xx_init_io to s3c2443.c
and make the s3c2443.h header obsolete.

Move s3c2443 specific code from s3c24xx_init_io to s3c2443.c
and make the s3c2443.h header obsolete.
