All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

[PATCH v2 03/41] ARM: s3c24xx: fix mmc gpio lookup tables

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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

[PATCH v2 05/41] ARM: s3c24xx: make S3C24XX_MISCCR access indirect

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

The clk driver uses both a function call into an exported
platform file and a direct register access to a hardcoded
virtual address for accessing the MISCCR register, both
become are a problem for a multiplatform kernel because
of the header file dependency.

Make this an indirect function call through platform data
instead.

[PATCH v2 06/41] ARM: s3c24xx: pass pointer to clk driver via platform data

Passing pointers directly as platform data is fragile and undocumented.
Better to create a platform data structure which explicitly documents

[PATCH v2 07/41] ARM: s3c24xx: simplify mach/io.h

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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 support 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.

[PATCH v2 09/41] usb: gadget: s3c-hsudc: remove platform header dependency

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

This should, really, be a PHY driver under drivers/phy, since the goal
is to make this platform-independent, might as well take the opportunity
to introduce a proper driver, no?

In theory, this is absolutely correct. I fear it will be hard to find anyone
to make a larger scale cleanup of the file however. As my old changelog
text says, there is only one board (smdk2416) in the kernel that registers
the device. My change was the minimum to keep it working during the
move to a multiplatform configuration, but if there is someone who has
the hardware and volunteers to make a proper phy driver, that would also
work.

As the board only exists as a reference for other boards, but none of those
made it into the kernel, we could alternatively just decide to drop the
driver. There is also a .dts file for the board, which is lacking a device node
for the udc (and the driver lacks DT support), so that board file could also
be dropped then, leaving only the DT version as a reference for the SoC.

All this is a work on a very old SoC with an unknown number of
current/real users. I don't have the hardware to test so I would prefer
to skip any big changes. As Arnd suggests, we could just drop this one
board and the driver... or if it does not harm/bother to much we could
keep it as is, just without platform header dependency. Someone still
might be using it.

Best regards,
Krzysztof

I don't mind deleting the entire thing if nobody is using it. The entire
history of the driver consists of only 65 commits and if you look at the
actual commits, there has been no real maintenance work on it for a long
time, most commits are regular janitorial work and updates due to
framework changes:

[PATCH v2 11/41] ARM: samsung: remove s3c_pm_debug_init()

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

On s3c24xx and s3c64xx, this is just a wrapper around
s3c_pm_debug_init_uart(), but this function does not exist on s5pv210,
which always uses an empty stub as CONFIG_SAMSUNG_ATAGS is normally
not set.

In a configuration that supports both s5pv210 and s3c64xx, we would
always call the s3c64xx function, which is probably incorrect when
running on s5pv210.

Remove the function call completely on s5pv210 and skip the wrapper on
s3c as a cleanup.

As a side-effect, the s3c64xx behavior is now always the same, regardless
of whether it is a DT-only configuration or both DT and ATAGS are
supported for booting.

[PATCH v2 12/41] ARM: samsung: make pm-debug platform independent

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

In particular, all the CPU checks need to be moved out of the common
code into platform specific files.

[PATCH v2 13/41] ARM: samsung: move CONFIG_DEBUG_S3C_UART to Kconfig.debug

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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

[PATCH v2 14/41] ARM: exynos: use private samsung_cpu_id copy

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 17/41] ARM: s5pv210: use private pm save/restore

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

The pm save/restore code is fairly small, so in order to
separate the s3c and s5p platforms, adding an s5p specific
copy instead of sharing it is actually easier.

completely independently, so split the two Kconfig symbols
CONFIG_PLAT_SAMSUNG and CONFIG_ARCH_S5PV210.

[PATCH v2 19/41] ARM: s3c64xx: remove mach/hardware.h

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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

[PATCH v2 20/41] ARM: s3c24xx: move regs-spi.h into spi driver

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 21/41] ARM: s3c24xx: move irqchip driver back into platform

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 22/41] ARM: s3c: adc: move header to linux/soc/samsung

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 23/41] ARM: s3c24xx: move spi fiq handler into platform

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

The fiq handler needs access to some register definitions that
should not be used directly by device drivers.

Since this is closely related to the irqchip driver anyway,
move it into the same place.

[PATCH v2 27/41] ASoC: samsung: s3c2412-i2s: avoid hardcoded S3C2410_PA_IIS

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

The constant requires indirectly including a machine header file,
but it's not actually used any more since commit 87b132bc0315 ("ASoC:
samsung: s3c24{xx,12}-i2s: port to use generic dmaengine API"), so
remove it completely.

[PATCH v2 28/41] ARM: s3c24xx: move iis pinctrl config into boards

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

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.

Well, it is now - that wasn't the case at the time.

[PATCH v2 29/41] ARM: s3c24xx: move s3cmci pinctrl handling into board files

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[krzk: Rebase and correct set_power in mach-h1940.c]
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

---

Changes since v1:
1. Minor whitespace changes,
2. mach-h1940.c already had set_power.

[PATCH v2 30/41] ARM: s3c24xx: include mach/irqs.h where needed

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 31/41] ARM: s3c24xx: spi: avoid hardcoding fiq number in driver

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 32/41] ARM: s3c24xx: bast: avoid irq_desc array usage

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 33/41] fbdev: s3c2410fb: remove mach header dependency

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 34/41] cpufreq: s3c24xx: split out registers

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
[krzk: Fix build by copying also S3C2410_LOCKTIME]
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

---

Changes since v1:
1. Copy also S3C2410_LOCKTIME to the driver.

[PATCH v2 35/41] ARM: s3c: remove cpufreq header dependencies

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 36/41] cpufreq: s3c2412: use global s3c2412_cpufreq_setrefresh

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 37/41] cpufreq: s3c24xx: move low-level clk reg access into platform code

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

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.

[PATCH v2 38/41] ARM: s3c24xx: stop including mach/hardware.h from mach/io.h

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

A number of other files rely on mach/map.h to be indirectly
included from mach/io.h through mach/hardware.h.

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

[PATCH v2 39/41] ARM: s3c: move into a common directory

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

s3c24xx and s3c64xx have a lot in common, but are split across three
separate directories, which makes the interaction of the header files
more complicated than necessary.

Move all three directories into a new mach-s3c, with a minimal
set of changes to each file.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
[krzk: Rebase, add s3c24xx and s3c64xx suffix to several files, add SPDX
       headers to new files, remove plat-samsung from MAINTAINERS]
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

---

Changes since v1:
1. Add s3c24xx and s3c64xx suffix to several files (headers and source
   files),
2. Add SPDX headers to newly created files,
3. Remove plat-samsung from MAINTAINERS.

[PATCH v2 40/41] ARM: s3c: make headers local if possible

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

A lot of header files are only used internally now, so they can be moved
to mach-s3c, out of the visibility of drivers.

[PATCH v2 41/41] MAINTAINERS: Add more name matches for Samsung SoC entries

[Krzysztof Kozlowski]

The Samsung SoC maintainer entry covers drivers and headers matching
"exynos" name but except that there are also files for S3C24xx, S3C64xx
and S5Pv210 SoCs.  These sometimes do not have a separate entry for a
driver maintainer thus might miss review.  Add them to the Samsung SoC
maintainer entry to cover all SoCs with name matches.

Thank you (& Arnd) for working on this!

PS I've checked fbdev related changes now and they all look good to me.
