| Subject | [PATCH 1/2] ARM: dts: Add TOPEET itop core board SCP package version |
| Message-ID | <s8Hea-4Xz-11@gated-at.bofh.it> |
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.

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.

What is meaning of "new introduce Exynos bus"?
Could you explain it to me?

It seems not very hard, I have sent new dts. But I am not sure I
understand it. For example I don't that C2C, PERIR and FSYS used for.

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.

| Subject | [PATCH 2/2] ARM: dts: add TOPEET itop elite based board |
| Message-ID | <s8YeZ-7mP-19@gated-at.bofh.it> |
| In reply to | #1467403 |
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
this weekend. After I have done the clock driver samsung s5m8767 regualtor.

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?
