These patches would add a support for a new exynos 4412 core
board with a base board.
Although the Samsung Exynos 4412 is a old chip but still powerful.
The main reason I keep to use it is the MFC. It is quite easy
to use the multimedia functions in samsung. I would like to
go into graphics part in the future.
Anyway, the TOPEET iTOP-4412 have many different version,
I only have Elite and Full version(The other one is Super version).
With two different Core board Chip pakcage(SCP or POP). As I
only have the SCP one, I would only offer support to SCP version.

The TOPEET itop is a samsung exnynos 4412 core board, which have
two package versions. This patch add the support for SCP version.
Currently supported are USB3503A HSIC, USB OTG, eMMC, RTC and PMIC.
The future features are in the based board. Also MFC and watchdog
have been enabled.

The TOPEET itop exynos 4412 have three versions base board. The
Elite version is the cheap one without too much peripheral devices
on it.
Currently supported are serial console, wired networking(USB),
USB OTG in peripheral mode, USB host, SD storage, GPIO buttons,
PWM beeper, ADC and LEDs.

The TOPEET itop exynos 4412 have three versions base board. The
Elite version is the cheap one without too much peripheral devices
on it.
Currently supported are serial console, wired networking(USB),
USB OTG in peripheral mode, USB host, SD storage, GPIO buttons,
PWM beeper, ADC and LEDs.

Since v4.8-rc1 MFC driver has been converted to generic reserved memory
bindings,
so samsung,mfc-* properties are obsoleted and no longer used. If you
want to use
MFC driver with reserved memory, please just add following line to your dts:
#include "exynos-mfc-reserved-memory.dtsi"
Please refer to dts of other boards for more examples.

I see, I would also enabled the bus_mfc and mfc entry.
I notice the new introduce Exynos bus. I need some time to add support it. I will send a new version later time(maybe you have to wait this weekend, sorry about that).

Changelog:
- v2:
- remove rtc node
the clock source driver is not done yet.
- add exynos-bus
- fix the MFC

The TOPEET itop is a samsung exnynos 4412 core board, which have
two package versions. This patch add the support for SCP version.
Currently supported are USB3503A HSIC, USB OTG, eMMC and PMIC.
The future features are in the based board. Also MFC and watchdog
have been enabled. The RTC clock source comes from PMIC, addtional
clk driver is needed.

The TOPEET itop exynos 4412 have three versions base board. The
Elite version is the cheap one without too much peripheral devices
on it.
Currently supported are serial console, wired networking(USB),
USB OTG in peripheral mode, USB host, SD storage, GPIO buttons,
PWM beeper, ADC and LEDs.

But could I set something like rootfs here ?
As the bootloader(old u-boot) offered by the vendor is brick, it is
impossible to save any something in u-boot.

Thank you for correct my spell mistake. I would resend a new version in

Yes, but then that is a user decision and shouldn't really be there
either. In other words, ether the bootloader should set bootargs
(which even a vendor u-boot should be able to do either directly or
the zImage can take it from the ATAGS) or a user can edit the dts and
carry that change.
However, there are probably plenty of examples in the kernel that
counter what I just said.

Yes, but you have to break the auto boot every time. I want to write a new u-boot for it, but I meet some problem with JTAG, it won't come soon.

I see than you. May I ask if I specific the rootfs bootargs of in dts, should you accept such patch?

The added the audio codec seems work now, but the audio sounds
still a little different to the original. But I didn't hear the sound
in the Android, I don't know whether it is qualified.
Also it lacks of full pinctrl for the sleep state.
Changelog:
- v3:
- fixing the rtc clock, using clock source from PMIC
- enable the tmu
- enable the fimc for elite board
- suuport the audio codec at elite board
- fixing minor bugs in the last commit
- v2:
- removing rtc node
the clock source driver is not done yet.
- adding exynos-bus
- fixing the MFC

The TOPEET itop is a samsung exnynos 4412 core board, which have
two package versions. This patch add the support for SCP version.
Currently supported are USB3503A HSIC, USB OTG, eMMC, rtc and
PMIC. The future features are in the based board. Also MFC and
watchdog have been enabled.

The TOPEET itop exynos 4412 have three versions base board. The
Elite version is the cheap one without too much peripheral devices
on it.
Currently supported are serial console, wired networking(USB),
USB OTG in peripheral mode, USB host, SD storage, GPIO buttons,
PWM beeper, ADC and LEDs.

The is not used for camera, I enabled it just for a colorspace

You shouldn't use underscores in node names.

The way you send emails is really messed up.
1. The v3 in "PATCH v3" should be present in all patches. Use -v3 for
format-patch.
2. Don't reply-in-to old thread. All your new patches are now under old
ones. They have same subject so this is highly confusing. I don't have a
clue which is a new one.
Best regards,
Krzysztof

1. 32 MHz? Usually it is 32 kHz... Did you test these DTS?
2. Please use existing S5M8767 driver.

The TOPEET itop is a samsung exnynos 4412 core board, which have
two package versions. This patch add the support for SCP version.
Currently supported are USB3503A HSIC, USB OTG, eMMC, rtc and
PMIC. The future features are in the based board. Also MFC and
watchdog have been enabled.

The TOPEET itop exynos 4412 have three versions base board. The
Elite version is the cheap one without too much peripheral devices
on it.
Currently supported are serial console, wired networking(USB),
USB OTG in peripheral mode, USB host, SD storage, GPIO buttons,
PWM beeper, ADC and LEDs. The WM8960 analog audio codec is also
enabled.
The FIMC is not used for camera currently, I enabled it just for a
colorspace convertor.

You are not making the review process easier... I asked for:
1. Not chaining the consecutive versions of patchset to the previous
ones. But now you removed chain replies totally (also from patches).
2. Versioning all patches.... but this is a resend of v1?
The changelog and cover letters disappeared...
Please, make it simple:
[PATCH v5 0/3] ARM: dts: exynos: some cover letter etc etc
\---[PATCH v5 1/3] ARM: dts: exynos: Add TOPEET itop core board SCP
\---[PATCH v5 2/3] ARM: dts: exynos: something more
\---[PATCH v5 3/3] ARM: dts: exynos: something even more
git format-patch and git send-email do this by default. In every
sensible mail program this looks like that and is easy to read.
I don't have a clue what happened to these patches and what is current
status...
Best regards,
Krzysztof

Don't you also need:
compatible = "samsung,s5m8767-clk";
here?
BTW Does anyone know why there are no users of
"samsung,s2mps11-clk" compatible in the tree
(commit 53c31b3437a6400c6ffc2c9315680217ad84cb6d
"mfd: sec-core: Add of_compatible strings for
clock MFD cells" added it in March 2014)?

No specific need... It is confusing but it is the same as with
regulators. The parent MFD driver creates children devices and match
drivers. The children (e.g. clk or regulator driver) look for hard-coded
subnode - clocks/regulators.
The compatible is actually not used in current form.

That is partially my fault. I got convinced by Lee Jones to add
compatibles even there are no users of them. The compatibles could be
added - for Arndale Octa and XU3/XU4. I think the only benefit of that
would be attaching the clock driver to the of_node.

Krzysztof
