s3c24xx has a custom implementation of the inb/outb family of I/O
accessors, implementing both general register access and ISA I/O port
through a multiplexer.
As far as I can tell, the first case has never been needed, and certainly
is not used now, as drivers only use inb/outb to actually driver ISA or
PCI port I/O.
Similarly, the special ISA support is limited to a single machine, the
Simtec Electronics BAST (EB2410ITX) with its PC/104 expansion connector,
all other machines could simply use the generic implementation from
asm/io.h that expects a single memory-mapped address range for byte,
word and dword access. As no other machines besides BAST actually selects
CONFIG_ISA, this is likely not even necessary.
As a cleanup, remove suport for the non-ISA access from the helpers,
and make the ISA access use the virtual address window that we use
elsewhere for PCI I/O ports. In configurations without the BAST machine,
this now falls back on the generic implementation from asm/io.h, but
the mach/io.h header is still relied on to include a number of other
header files implicitly.

The resources are correctly initialized, so just use them
instead of relying on hardcoded data from platform headers.

Generic comment to all patches - you seem to break commit msg lines
slightly too early. In certain cases it makes them unnecessarily longer.
Maybe your editor has to be fixed to wrap at 75 column.

I tend to use '/usr//bin/fmt' with the default setting. I think the idea of that
default is that an email reply with added '>' characters doesn't immediately
have to reflow the text.

There is no real phy driver, so s3c-hsudc just pokes the registers
itself. Improve this a little by making it a platform data callback
like we do for gpios.
There is only one board using this driver, and it's unlikely
that another would be added, so this is a minimal workaround.

Copy paste error - phy_init().
Are here (and in previous usb gadget patch) any dependencies? If so, I
would need an ack to take it through samsung-soc.

Fixed, thanks!

Yes. This patch should not depend on anything else, but later patches
in the series depend on it, so I'd like to keep everything together.

The pm-debug code is one of the few things shared between s3c24xx/s3c64xx
and the newer s5pv210. In order to make s5pv210 independent of plat-samsung,
change the common bits of this code to no longer reference the s3c specific
bits.

Your patch is not equivalent here. If there is a reason behind removal
of UART init (e.g. not needed), I prefer to make it in separate patch.
Rest looks good.

It is equivalent, but the reason is a bit subtle:
The definition looks like
#ifdef CONFIG_SAMSUNG_ATAGS
#include <plat/pm.h>
#include <mach/pm-core.h>
#else
static inline void s3c_pm_debug_init_uart(void) {}
#endif
void s3c_pm_debug_init(void)
{
/* restart uart clocks so we can use them to output */
s3c_pm_debug_init_uart();
}
On s5pv210, CONFIG_SAMSUNG_ATAGS is never set, so this
function does not do anything. Splitting the change out into a
separate patch to explain that is a good idea, I'll do this.

Before we can plat-samsung from the individual platforms,
this one has to get moved to a place where it remains
accessible.

The only part of plat-samsung that is shared with arch-exynos
is the CPU identification code.
Having a separate exynos_cpu_id variable makes the two completely
independent and is actually a bit less code in total.

How about keeping the S3C_VA and S3C_ADDR_BASE macros/defines and using
them? They still appear in arch/arm/include/debug/exynos.S so they could
be integrated into one header, unless you plan to remove it in further
patches.

Ok, done now.

I don't think it actually helps, but it doesn't hurt either:
arch/arm/include/debug/exynos.S cannot #include any mach/*.h header files,
so the definition has to remain duplicated, unless I'm missing something.
Also, the addresses should be completely independent, as long as the virtual
address for the uart does not overlap with the virtual address for the chipid.
One possible cleanup here would be to completely remove the S5P_VA_CHIPID
static map and use ioremap(), but doing that requires that the first call to
soc_is_exynosXXXX() happens after the ioremap.

Now that no code in arch/arm is shared between mach-exynos and the
others, make the split formal.

You need to keep PLAT_SAMSUNG because of additional architectures, so
follow pattern from DEBUG_S3C_UART2.

Are you sure? I think my version is correct: for UART2, the
"PLAT_SAMSUNG || ARCH_EXYNOS" is equivalent to "s3c24xx || s3c64xx ||
s5pv210 || exynos", which keeps the existing behavior unchanged.
For UART3, the "PLAT_SAMSUNG && ..." is redundant, this is already
limited to "s5pv210 || exynos", which my patch keeps. Changing it to
"PLAT_SAMSUNG || ..." would allow selecting the symbol on s3c24xx
and s3c64xx, which presumably is not valid.

This is the only part of plat-samsung that is really
shared between the s3c and s5p ports. Moving it to
drivers/soc/ lets us make them completely independent.

Use guard name prefix consistent with other files, so:
__LINUX_SOC_SAMSUNG_S3C_PM_H
Rest looks good.

CONFIG_EXYNOS_CPU_SUSPEND looks unrelated and seems to be not needed at
all. Can you remove it in separate patch?

Ok, done.
As the constant is only used in arch/arm/mach-s5pv210/pm.c and the
s5pv210_dt_restart() function, I think it would be best to use ioremap()
here and remove the constant as well as s5pv210_fdt_map_sys() and
s5pv210_dt_map_io().
That can clearly be a follow-up patch.

These can be build completely independently, so split

I'd mention the two symbols' names you're working on in the commit log.
I guess it's about PLAT_SAMSUNG and ARCH_S5PV210. And I wouldn't call it
"split" which IMHO suggests there was only one symbol before.
Maybe:
Don't imply PLAT_SAMSUNG if ARCH_S5PV210 is enabled
would be a better subject line?

Would it make more sense to make this
plat-$(PLAT_SAMSUNG) += samsung
(in a separate patch)? Hmm, it seems there is no plat-y for
PLAT_S3C24XX=y builds. Is this intended? If yes, the directory name
containing "samsung" suggests something that seems untrue.
Best regards

By the end of the series, the plat-samsung directory is completely
removed (folded into mach-s3c), so that would only add more
churn for the same result I think.

fine for me. The background of my question was me wondering if builds
for PLAT_S3C24XX=y (before your patch series) don't need plat-samsung.

What I found is that the DT-based platforms (exynos and s5p) need almost nothing
from plat-samsung, while the board files and the s3c24xx/s3c64xx power
management
needs almost all of it.

I don't see a problem here, the patch should not change the behavior at all.
The whole entry now looks like:
config DEBUG_S3C_UART0
depends on PLAT_SAMSUNG || ARCH_S5PV210 || ARCH_EXYNOS
select DEBUG_EXYNOS_UART if ARCH_EXYNOS
select DEBUG_S3C24XX_UART if ARCH_S3C24XX
select DEBUG_S3C64XX_UART if ARCH_S3C64XX
select DEBUG_S5PV210_UART if ARCH_S5PV210
bool "Use Samsung S3C UART 0 for low-level debug"
so this will work as before with any of ARCH_EXYNOS, ARCH_S3C24XX,
ARCH_S3C64XX and ARCH_S5PV210.
What am I missing?

Ah, everything is OK, I mixed up removed with added line so it looked
reversed (removal of ARCH_S5PV210).
Looks good.

This header is empty and conflicts with the s3c24xx version
of the same file when we merge the two, so stop including it.

The file is mostly specific to the driver, the few bits that
are actually used by the platform code get moved to mach/map.h
instead.

Ok, changed to __SPI_S3C2410_H, this seems to be the most common format
in spi drivers.

It was a good idea to move it out at first, but the irqchip code
is still tightly connected to the s3c24xx platform code and uses
multiple internal header files, so just move it back for the
time being to avoid those dependencies.

There are multiple drivers using the private adc interface.
It seems unlikely that they would ever get converted to iio,
so make the current state official by making the header file
global.
The s3c2410_ts driver needs a couple of register definitions
as well.

The s3c_gpio_cfgall_range() function is an internal interface of
the samsung gpio driver and should not be called directly by drivers,
so move the iis pin initialization into the boards.
Note that the s3c2412-i2s driver has no boards using it in
mainline linux, the driver gets selected for the jive machine
but is never instantiated.

This is not entirely equivalent move as before this was probe (so being
executed also on rebinds) and now it is init. I guess it should not make
any difference so let it be.

Right, I've added an explanation in the changelog text now:
The s3c_gpio_cfgall_range() function is an internal interface of the
samsung gpio driver and should not be called directly by drivers, so
move the iis pin initialization into the boards.
+This means the pin configuration is only run once at early boot, rather
+than each time the driver binds, but the effect should be the same.

The leds-s3c24xx driver calls the private s3c_gpio_setpull()
interface for each gpio line, but doing this requires
access to the machine header files.
Move those calls into the machine init functions for any
board that uses the driver.

Cc: linux-samsung-soc, linux-arm-kernel, linus.walleij,
Arnd Bergmann, linux-kernel, linux-mmc
Rather than call the internal s3c_gpio_cfgall_range() function
through a platform header, move the code into the set_power
callback that is already exported by the board, and add
a default implementation.
In DT mode, the code already does not set the pin config,
so nothing changes there.

It looks good:
Acked-by: Linus Walleij <linus.walleij@linaro.org>
It would feel better if someone was actually testing it on these
boards. I see Ben is listed as maintainer so I bet he will
pull the board out :)

Preparing for a later conversion to sparse IRQs, this ensures that
the mach/irqs.h header is still visible in files that reference
an IRQ number.

The IRQ_EINT0 constant is a platform detail that is
defined in mach/irqs.h and not visible to drivers once
that header is made private.
Since the same calculation already happens in s3c24xx_set_fiq,
just return the value from there.

Once we move to sparse irqs, the irq_desc[] array is no
longer accessible, so replace the two uses in bast-irq.c.
The first one can use irq_to_desc(), the second one seems
completely unneeded as we already have a pointer to the
correct descriptor.

The gpio controller names differ between s3c24xx and s3c64xx,
and it seems that these all got the wrong names, using GPx instead
of GPIOx.

The s3c2410fb driver is too deeply intertwined with the s3c24xx
platform code. Change it in a way that avoids the use of platform
header files but having all interface data in a platform_data
header, and the private register definitions next to the driver
itself.
One ugly bit here is that the driver pokes directly into gpio
registers, which are owned by another driver. Passing the
mapped addresses in platform_data is somewhat suboptimal, but
it is a small improvement over the previous version.

Nits: indentation before/after '=' looks wrong. Tab should be
before '=', one space after.

Ok, fixed now for the four boards that had inconsistent indentation --
jive, mini2440, smdk2440, and rx1950. Unfortunately each board
seemed to have its own way of doing this.

Each of the cpufreq drivers uses a fixed set of register
bits, copy those definitions into the drivers to avoid
including mach/regs-clock.h.

The cpufreq drivers are split between the machine directory
and the drivers/cpufreq directory. In order to share header
files after we convert s3c to multiplatform, those headers
have to live in a different global location.
Move them to linux/soc/samsung/ in lack of a better place.

Can you also update the header guard names to match new location?

Neither of those files had header guards, added them now.

There are two identical copies of the s3c2412_cpufreq_setrefresh
function: a static one in the cpufreq driver and a global
version in iotiming-s3c2412.c.
As the function requires the use of a hardcoded register address
from a header that we want to not be visible to drivers, just
move the existing global function and add a declaration in
one of the cpufreq header files.

I think that it does not cover the !CONFIG_S3C2412_IOTIMING case.
Either you need to provide also the empty stub or add default=y to
S3C2412_IOTIMING. Otherwise cpufreq driver might end up without this.
Best regards,

S3C2412_IOTIMING is not currently optional, it always gets selected
by ARM_S3C2412_CPUFREQ, unlike S3C2410_IOTIMING which is
only selected by specific boards for reasons I don't understand.

There are two functions in this file that are never called from
anywhere else, so they should be static to allow the compiler
to optimize it better and not pollute the global namespace.

Rather than have the cpufreq drivers touch include the
common headers to get the constants, add a small indirection.
This is still not the proper way that would do this through
the common clk API, but it lets us kill off the header file
usage.

Reduce this to the minimal plat/map-base.h and add explicit
includes everywhere else.

I think I added this one for S3C24XX_VA_CLKPWR, which is in
plat/map-s3c.h

This was the result of a botched rebase: The patch was initially
at the start of the series where the #include was still required
but later moved to the end behind the patch that used to remove
it again.

Same here.
Thanks for taking a look, I'll fix it all up tomorrow.

Thanks for the patch!
Just one minor nit: It doesn't look very nice to pass a function
pointer directly as platform data. Could we have a struct defined
instead - with a kerneldoc comment describing the function pointer
field?
Best regards,
Tomasz
