Hello,
This is a third version of my patch series adding support for camera interface,
video output and video processing IP contained in Samsung's S3C/S5P SoCs.
Changes since v1:
- support for multiple SoC variants through the platform device name overriding
(S5PC100 and SPV210 version definitions included)
Changes since v2:
- reworked register definition, minor synchronization fixes, whitespace cleanup
- removed support for FIFO mode output to the lcd controller due to
hardware limitations (removed fifo link and platform data setup code
and v4l2_subdevice in s3c-fb driver)
The following patch series contains:
[PATCH v3 1/8] ARM: Samsung: Add register definitions for Samsung S5P SoC camera interface
[PATCH v3 2/8] v4l: Add driver for Samsung S3C/S5P SoC video postprocessor
[PATCH v3 3/8] ARM: Samsung: Add platform definitions and helpers for FIMC driver
[PATCH v3 4/8] ARM: Samsung: Add common Aquila and GONI code
[PATCH v3 5/8] ARM: s5pv210: enable FIMC on Aquila
[PATCH v3 6/8] ARM: s5pv210: enable FIMC on Goni
[PATCH v3 7/8] ARM: S5PC100: enable FIMC on SMDKC100
[PATCH v3 8/8] ARM: s5pv210: Override FIMC driver name on Aquila board
Best regards,

This driver exports a video device node per each camera interface/
video postprocessor (FIMC) device contained in Samsung S3C/S5P SoC series.
The driver is based on v4l2-mem2mem framework.

From: Sylwester Nawrocki @ 2010-07-23 16:21 UTC (permalink / raw)
To: linux-arm-kernel
This driver exports a video device node per each camera interface/
video postprocessor (FIMC) device contained in Samsung S3C/S5P SoC series.
The driver is based on v4l2-mem2mem framework.

FIMC (CAMIF) device is a camera interface embedded in S3C/S5P Samsung
SOC series. It supports ITU-R BT.601/656 and MIPI-CSI2 standards,
memory to memory operations, color conversion, resizing and rotation.

Just setup-fimc.c is enough...
I don't know why we need common-aquila-goni now.
And your following patches in this patch-set perfectly same except just
name.
[PATCH v3 5/8] ARM: s5pv210: enable FIMC on Aquila
[PATCH v3 6/8] ARM: s5pv210: enable FIMC on Goni

The alternative was to have identical clock setup code in both mach-aquila
and mach-goni files.

One is for Aquila and one is for Goni, sorry, I don't understand what do
you mean here... Would you prefer them to be combined into one patch?

Bootloader is not setting up clocks correctly and defaults do not work.
It's not only for fifo, fimc doesn't work at all without this.

What would you propose as the alternative? Have duplicate code in both machine

On the other hand, arch/arm is getting soo big that we need to do
something about this - and one solution is to avoid unnecessary
definitions that we're not using.
Another good idea is to put definitions along side the drivers which
they're relevant to - maybe in a local driver-name.h file which
driver-name.c includes, or maybe even within driver-name.c if they're
not excessive. This has the advantage of distributing the "bloat" to
where its actually used, and means that the driver isn't dependent so
much on arch/arm or even the SoC itself.
Take a look at arch/arm/mach-vexpress/include/mach/ct-ca9x4.h and
arch/arm/mach-vexpress/include/mach/motherboard.h - these are the only
two files which contain platform definitions which are actually used
for Versatile Express. Compare that with
arch/arm/mach-realview/include/mach/platform.h which contains lots
more...

Well, with FIMC driver we just followed the style from other Samsung
drivers. Just take a look at video/s3c-fb or usb/gadget/s3c-hsotg.c.
I personally like to keep the same style for all drivers for Samsung
IPs. Changing the style of all of them requires some amount of work,
that would delay this particular driver even more so we will definitely
miss the merge window.

Very much appreciated from my side. It is very hard to sync changes that
happen via arm trees when merging from my tree. There were several cases
in the past were I needed to coordinate with an ARM maintainer about when
he would merge from his tree, as the patches I had on media tree were
highly dependent on the patches at arch.
On several cases, I suspect that we had git bisect breakages (compilation
or driver miss-functioning) due to those sync issues between two trees.
A per-driver *.h file makes things easier, as such header file can be
merged/maintained together with the subsystem tree where the driver belongs.

This is patch is a v3 version rebased onto latest kgene/for-next tree.
New entries in map.h files has been sorted by the physicall address.
I'm resending this patch on behalf of Sylwester who is on holidays this

* [PATCH v4 3/8] ARM: Samsung: Add platform definitions and helpers for FIMC driver
@ 2010-08-02 11:57 ` Marek Szyprowski
0 siblings, 0 replies; 69+ messages in thread
From: Marek Szyprowski @ 2010-08-02 11:57 UTC (permalink / raw)
To: linux-arm-kernel
From: Sylwester Nawrocki <s.nawrocki@samsung.com>
FIMC (CAMIF) device is a camera interface embedded in S3C/S5P Samsung
SOC series. It supports ITU-R BT.601/656 and MIPI-CSI2 standards,
memory to memory operations, color conversion, resizing and rotation.

This is patch is a v3 version rebased onto latest kgene/for-next tree.
New entries in map.h files has been sorted by the physicall address.
I'm resending this patch on behalf of Sylwester who is on holidays this
week.
Best regards

That's a separate problem - one which occurs when there's platform
code in arch/arm/ which shares a common data structure with driver
code under drivers/.
I don't think there's an easy resolution to that one, because if
you split the arch/arm/ change (which may depend on other arch/arm/
changes) from the drivers/ change, someone ends up losing no matter
where the header file with the common data structure is placed.
One answer to that is to kill the idea that every ARM architecture
needs to define their own watchdog platform data - and instead
replace it with a shared watchdog_platform_data structure, much like
the flash_platform_data structure in arch/arm/include/asm/mach/flash.h
(which'd would be nice to be under include/linux ...)

What I'm suggesting is what's been pretty standard in Linux for a long
time. Take a look at: drivers/net/3c503.[ch], or for a more recent
driver, drivers/net/e1000/*.[ch]. Or drivers/mmc/host/mmci.[ch]
Putting definitions which are only used by one driver in arch/arm/*/include
is silly.

To use one style is better for reading, merge conflict handling and so on...
The style means to add S5P_PA_XXX after S3C_PA_XXX with C100 case or to
modify above C100 case like this.

This is just for your information...
I'm working on handling plat device in case of various # of each AP FIMC
with CONFIG_NR_FIMC...
So in this case, all of plat data for FIMC will be merged into
'plat-s5p/dev-fimc.c' or 'devs.c' later.
...but I'm not sure some stuff...anyway...

To use one style is better for reading, merge conflict handling and so on...
The style means to add S5P_PA_XXX after S3C_PA_XXX with C100 case or to
modify above C100 case like this.

This is just for your information...
I'm working on handling plat device in case of various # of each AP FIMC
with CONFIG_NR_FIMC...
So in this case, all of plat data for FIMC will be merged into
'plat-s5p/dev-fimc.c' or 'devs.c' later.
...but I'm not sure some stuff...anyway...

If you want now, just 'dev-fimc.c' is ok...but in that case, need to add
'#ifdef CONFIG_S5P_DEV_FIMCX' in there..and 'OR' in Makefile for dev-fimc.o

I agree with Russell's opinion.
I don't want to add unnecessary(or unavailable in arch/arm) definitions in
arch/arm/*/include

Changes since v4:
- addressed all minor style issues reported by Kukjin Kim
Changes since v3:
- rebased onto latest kgene/for-next tree
- new entries in map.h files has been sorted by the physicall address
I'm sending this patch on behalf of Sylwerster who is on holidays this
week.

Should being in driver...I don't know why we should enable fimc clock in here.
Basically, each driver clock should be enabled in each drivers...

If this is only for Aquila and GONI, should be common_aquila_goni_fimc_clk_init().
But it's quite long :-( ... anyway, as I said, I don't think this is only for Aquila and GONI.

setup-fimc.c, but need to sort it out so that all machines can use that.
Thanks.

I mean this is just for fimc clock setting...this is not only for Auqila and GONI machines even though need to update to be used in other machines.

Is not there in case of using 'mout_mpll' as parent clock?
