We decided to use 0x3000'0000 as base memory address on S5PC1XX SoCs
(s5pc100 and s5pc110).
A patch to u-boot that configures SMDKC100 board and sets base memory
as 0x3000'0000 has been already posted.

Samsung S5PC100 and S5PC110 SoCs differs a lot in register map and other
core platform definitions, so it is not possible to have both SoCs in
the current platform framework without runtime hacks. To address this
issue a sub-platform has been introduced, so each SoC in sub-platform
can have its own set of include files (register map, irq&gpio
definitions, etc)

CLK_OTHER register block is specific for S5PC100 SoC, so move the
definition to mach-s5pc100/cpu.c. Size of CLK and PWR register block is
different on S5PC100 and S5PC110, thus new defines are introduced.
Clock and pll hierarchy is completely different between S5PC100 and
S5PC110 SoCs, so move related includes to new sub-platform and rename
plat-s5pc1xx/clocks.c and plat-s5pc1xx/s5pc100-clock.c to
s5pc100-clocks.c (periperal clocks definition) and s5pc100-plls.c (core
pll hierarchy definition).

S5PC100 GPIO chip definitions has been hidden under sub-platform #ifdef
CONFIG_CPU_S5PC100. Also a new S5PC1XX_GPHx() macros has been introduced
to cover common external interrupt gpio lines (for common code).

All device helpers that are defined in plat-s5pc1xx are S5PC100
specific. This patch moves them to mach-s5pc100 directory to make use of
newly created sub-platform support.

Frame buffer register block on S5PC100 and S5PC110 differs slightly.
This patch moves all register definitions that are common for S5PC100
and S5PC110 to plat-s3c/plat/regs-fb-v5.h.

Not just about this c110 patch: I think this string comparison thing
isn't very neat.
I think we'd better be doing it by indexing into an array of clock
names(which can be
defined in some platform specific code).

I don't mind changing to using a table, but the table is probably best
off here, closest to the UART drivers in question.

well as per current implementation of drivers/serial/samsung.c we can't
do much about it.
Ideally, each SoC(if not yet, maybe in future) can have different
number/names of possible source clocks for signal generation. Let us
not depend upon even defaults(fclk, pclk etc)
Let each platform code(SoC specific) define names of all possible
source clocks and let the board init code pass on the potential source
clocks by some bit-mask(or some other mechanism) while setting the
platform data.
The samsung.c could then simply go thru the array of source clock
names and the bit-mask, in platform_data, while selecting the best possible
source for the baud rate under consideration.

This is going to set off warnings from a clock API point of view -
passing clock names around in platform data is usually a sign that
something is very wrong. Keeping the mapping inside the clock API
(still controlled by the board driver but by telling the clock API that
device X should use clock Y).

no clock pointer needs to be passed, just a pointer to an array of _strings_
There is no need to even include any clock header in platform code
for the purpose.

Yes, that's what I was commenting on - like I say, passing clock names
tends to set off the same alarm bells as passing a struct clk. Like I
say, the general model for this has been that the fixups will be done by
having the machine code talk to the clock API ratehr than bouncing the
data about the clock to use through the driver.

The case here is that UART controller can source from various platform clocks
to generate the UART clocks. The drivers/serial/samsung.c chooses a source
clock that can result in closest match to the requested rate.
How could we do that from machine code(except for writing callbacks for each
machine using the SoC)?
Or maybe i cud understand better looking at some example.
Cud u suggest some please?

I can't think off the top of my head of anything which does this
dynamically (rather than just choosing a clock at startup time). OMAP
might have something since they seem to have the most advanced of the
current implementations.
Off the top of my head it sounds like the muxing ought to be pushed into
the clock API completely - the problem of picking the best match for the
current use case isn't unique to the serial driver by any stretch of the
imagination. The serial driver would then end up just seeing the output
of the mux it uses, with the clock API dealing with working out which of
the sources can deliver the best match.

I'm not sure what you're commenting on precisely, but the Samsung code as
a whole doesn't use the clk API very well, and I suspect that is starting
to cause people to have to pass clock names around.
I've tried to persuade Ben to tidy this up and convert over to clkdev
before it becomes too big a problem, but I've had little success. I
suspect it's now grown too big to be tackled sanely.

That's what I'd thought originally but it's not quite the problem here.
The issue is that Samsung serial port clock is chosen from a mux and the
logic to select which of the inputs to that mux should be used is in the
serial driver. This means that if the set of parent clocks changes then
the serial driver needs to be told what they are.
My suggestion was to push this logic down into the clock API so the
serial driver just requests a rate and then clock API picks the best
option from the mux. As well as being nicer from the clock API point of
view this would also allow other drivers to use the same logic since
these muxes are a standard idiom for Samsung SoCs.

clkdev would be nice but I don't think it'd deal with the issue here.

Yes, I agree with that approach.

just to add to the info: unlike system clocks and mux'es which are controlled
by registers of a dedicated clock/system controller, this uart mux is
managed by bits of some register of the UART controller.

how transparently could we add this 'uart-mux' into the clock API, provided
that the register space ioremap'ing is done in the uart driver, is to be seen.

What if a device does not operate properly when clocked from one of the
available clock sources (lets say machine specific problem)? There must
be a way of setting which clock(s) should not be considered when calculating
best choice for particular device.

Have the machine driver tell the clock API about this - that's what I
was suggesting originally before I realised there was the mux managment
logic in there.

That shudn't be a concern. for example, if some machine doesn't provide clock
at some PAD, which could be used as a source, then the clock API wud read the
clock as 0 and the calculations wudn't pick that source up. Likewise, any such
'unusable' clock in the machine wud be marked by having invalid(0) rates.
The problem is moving this uart-mux into the the Clock API.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds register map for S5PC110 sub-platform.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds CPU initialization code for S5PC110 sub-platform.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds clocks and plls definition for S5PC110 SoCs.

From: Kyungmin Park <kyungmin.park@samsung.com>
Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds interrupt support on S5PC110 SoCs. Unlike S5PC100,
S5PC110 has 4 VICs, so the S5PC110 specifi virtual memory area is
extended to cover VIC3 register block.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds gpiolib support for S5PC110 sub-platform.

these follwing functions could have had their info added to an extended
gpio structure, say struct s5p_gpio_chip and had a s3c_gpio_chip embededded in
it, which would make the code simpler,
ie:
struct s5p_gpio_chip {
struct s3c_gpio_chip chip;
unsigned int gpio_start;
unsigned int gpio_groupl
};
and then you could have gone chip->info easily.

Thanks for suggestion! I will rewrite this and split gpio lib support into
separate files for each sub-platform and send new patches soon.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds required I2C platform helpers. S5PC110 SoCs has 3 I2C
controllers.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch enables S5PC110 sub-platform.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds common framebuffer device helpers and register defines
for S5PC110 sub-platform.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds support for SMDKC110 evaluation board. The board can be
obtained from Meritech (http://www.meritech.co.kr).

running these through checkpatch first would have been a good idea:
fyi, these need fixing:

Hello,
This preliminary patch series adds support for Samsung S5PC110 SoC.
S5PC110 belongs to S5PC1XX family (CortexA8 ARM core), but differs in
many places from the S5PC100 SoC: new memory map, different clock
hierarchy, new gpio banks and much more powerful integrated peripherals.
Such differences cannot be easily handled in the current Samsung
machine&platform framework. To avoid duplication of code and adding yet
another plat-* directory, we decided to introduce sub-platforms in
the current s5pc1xx platform.
First 8 patches prepare s5pc1xx platform code for introduction of the
new sub-platform approach. Then in the next 11 patches all core
functions and drivers are subsequently added, so S5PC110 sub-platform
gets similar level of support as S5PC100. The last patch updated
MAINTAINERS information.
This patch series has been prepared against latest ARM Kernel tree from
http://ftp.arm.linux.org.uk/pub/linux/arm/kernel/git-cur/linux-2.6-arm.git/
This is the second version of this patch series. The following issues
reported by Ben have been fixed: gpiolib support has been rewriten, more
SoC specific files have been moved to mach-s5pc* directories (gpio chip,
plls and clocks definitions). Also author/sender issues are resolved.
The clock issue in S5PC110 driver has not been addressed. The driver
uses clock API in the same way as it is handled in other Samsung UART
drivers. This clock issue should be resolved in a separate patch which
would fix all Samsung drivers at once. Until then we would like to use
the current approach.
This patch series includes:

[PATCH 02/20] ARM: S5PC1XX: create sub-platform for S5PC100 SoCs

We decided to use 0x3000'0000 as base memory address on S5PC1XX SoCs
(s5pc100 and s5pc110).
A patch to u-boot that configures SMDKC100 board and sets base memory
as 0x3000'0000 has been already posted.

We decided to change the base memory address to 0x30000000 to be able to
support systems with 512MB in the second bank (DRAM1) without using HIMEM.
In first bank (DRAM0), which is integrated with SOC (POP) we would always
have no more than 256MB of memory. If we would leave the first bank at
0x2000'0000, we would lose 256MB of kernel virtual address space for
useless memory hole. With this patch (and proper u-boot) we can run kernel
on systems with max 256MB + 512MB of memory in 1GB kernel/3GB userspace
address space configuration.
Best regards

Samsung S5PC100 and S5PC110 SoCs differs a lot in register map and other
core platform definitions, so it is not possible to have both SoCs in
the current platform framework without runtime hacks. To address this
issue a sub-platform has been introduced, so each SoC in sub-platform
can have its own set of include files (register map, irq&gpio
definitions, etc)

CLK_OTHER register block is specific for S5PC100 SoC, so move the
definition to mach-s5pc100/cpu.c. Size of CLK and PWR register block is
different on S5PC100 and S5PC110, thus new defines are introduced.
Clock and pll hierarchy is completely different between S5PC100 and
S5PC110 SoCs, so move related includes to new sub-platform and rename
plat-s5pc1xx/clocks.c and plat-s5pc1xx/s5pc100-clock.c to
s5pc100-clocks.c (periperal clocks definition) and s5pc100-plls.c (core
pll hierarchy definition).

All device helpers that are defined in plat-s5pc1xx are S5PC100
specific. This patch moves them to mach-s5pc100 directory to make use of
newly created sub-platform support.

Framebuffer register blocks on S5PC100 and S5PC110 differ only slightly.
This patch moves all register definitions that are common for S5PC100
and S5PC110 to plat-s3c/plat/regs-fb-v5.h.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds clocks and plls definition for S5PC110 SoCs.

From: Kyungmin Park <kyungmin.park@samsung.com>
Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds interrupt support on S5PC110 SoCs. Unlike S5PC100,
S5PC110 has 4 VICs, so the S5PC110 specifi virtual memory area is
extended to cover VIC3 register block.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds gpiolib support for S5PC110 sub-platform.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds required I2C platform helpers. S5PC110 SoCs has 3 I2C
controllers.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds common framebuffer device helpers and register defines
for S5PC110 sub-platform.

Samsung S5PC110 SoC are newer Samsung SoCs. Like S5PC100 they are based
on CortexA8 ARM CPU, but have much more powerfull integrated periperals.
This patch adds support for SMDKC110 evaluation board. The board can be
obtained from Meritech (http://www.meritech.co.kr).
