Samsung Exynos 7870 (codename: Joshua) is an ARM-v8 system-on-chip that was
announced in 2016. The chipset was found in several popular mid-range to
low-end Samsung phones, released within 2016 to 2019.
This patch series aims to add support for Exynos 7870, starting with the
most basic yet essential components such as CPU, GPU, clock controllers,
PMIC, pin controllers, etc.
Moreover, the series also adds support for three Exynos 7870 devices via
devicetree. The devices are:
* Samsung Galaxy J7 Prime - released 2016, codename on7xelte
* Samsung Galaxy J6 - released 2018, codename j6lte
* Samsung Galaxy A2 Core - released 2019, codename a2corelte
Additional features implemented in this series include:
* I2C - touchscreen, IIO sensors, etc.
* UART - bluetooth and serial debugging
* MMC - eMMC, Wi-Fi SDIO, SDCard
* USB - micro-USB 2.0 interface
Build dependencies are in these sub-series:
* pmu-clocks A https://lore.kernel.org/all/20250301-exynos7870-pmu-clocks-v5-0-715b646d5206@disroot.org/

Exynos7870 is an arm64 SoC manufactured by Samsung and announced in
2016. It is present in multiple mid-range Samsung phones and tablets.
Add basic devicetree support for the SoC, which includes CMUs, pin
controllers, I2C, UART, DW-MMC, and USB-DRD.

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
This patch series was applied (using b4) to base:
Base: using specified base-commit 29e7bf01ed8033c9a14ed0dc990dfe2736dbcd18
If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

This is not the reason to send new version. It only creates unnecessary
traffic and more effort on my side to filter out versions. Read
submitting patches regarding handling the tags.

So this patchset waits? Ping me or resend when your dependencies are
merged. If resending then of course explain why and update dependencies
list.

Hi, all dependencies are now available in next. I believe you should
be able to merge it now.
Thanks a lot!

Why are these two separate device nodes, instead of one for two ranges?
Does device has somehow two independent memory controllers?

If there is going to be any resend, drop redundant blank line.

This is from Galaxy J6:
memory@40000000 {
device_type = "memory";
reg = <0x0 0x40000000 0x3d800000>;
};
memory@80000000 {
device_type = "memory";
reg = <0x0 0x80000000 0x40000000>;
};
changes to
memory@40000000 {
device_type = "memory";
reg = <0x0 0x40000000 0x3d800000>,
<0x0 0x80000000 0x7d800000>;
};
I assume I have changed it correctly? `free -h` displays the full
and correct memory capacity.
