[PATCH v2 0/4] Add minimal Samsung Galaxy S20 Series board, SM-G981B and SM-G980F support

[PATCH v2 0/4] Add minimal Samsung Galaxy S20 Series board, SM-G981B and SM-G980F support

[Umer Uddin]

Hi folks,

This series adds initial support for the Samsung Galaxy S20 Series, also
initial board support for the Samsung Galaxy S20 5G (SM-G981B)
codenamed x1s and the Samsung Galaxy S20 (SM-G980F) codenamed
x1slte.

The S20 Series feature a lot of similarities in their configuration
and internally Samsung named the common devicetrees in their
downstream kernel 'hubble', please note hubble excludes the
S20 FE series and Note20 series.
The device trees have been tested with dtbs_check W=1
and results in no warnings.

This initial bringup consists of:
 * pinctrl
 * gpio-keys
 * simple-framebuffer

This is enough to reach a shell in an initramfs. More platform support
will be added in the future.

Just like SM-N981B, the preferred way to boot the upstream kernel is
by using a shim bootloader, called uniLoader [1], which works around
some issues with the stock, non-replacable Samsung S-LK bootloader.
For example, the stock bootloader leaves the decon trigger control
unset, which causes the framebuffer not to refresh.

Device functionality depends on the patch series from Igor Belwon:
"Add minimal Exynos990 SoC and SM-N981B support"

[1] https://github.com/ivoszbg/uniLoader

Changes in v2:
 - Add Samsung Galaxy S20 into device tree bindings
 - Add support for Samsung Galaxy S20 as well as the 5G variant now
 - Fix typo in Samsung Galaxy S20 5G commit message

Kind regards,
Umer

It does not look like you tested the bindings, at least after quick
look. Please run 'make dt_binding_check' (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

Best regards,
Krzysztof

[PATCH v2 2/4] arm64: dts: exynos: Add initial support for Samsung Galaxy S20 Series boards (hubble)

Add initial support for the Samsung Galaxy S20 Series (hubble) phones.
They were launched in 2020, and are based on the Exynos 990 SoC.
The devices have multiple RAM configurations,
starting from 8GB going all the way up to 16GB for the S20 Ultra devices.

This device tree adds support for the following:

- SimpleFB
- 8GB RAM (Any more will be mapped in device trees)
- Buttons

If I am counting correctly, that's only 8 GB, not 12.

8 GB RAM, so the memory map should not be the same (and should not be in
DTSI file).

Hi Krzysztof,

Thank you for the review.
All hubble devices actually do
have the first 8GB of RAM mapped the same, I have personally
checked this, by getting fdt dumps from /sys/firmware/fdt
and checking all of the memory nodes.

Best regards,
Umer

What about remaining 4 GB on X1S?

On x1s, the remaining memory is mapped in the device specific dtsi.

Then it proves that this is not correctly placed - not a shared part of
boards. Remove it from DTSI.

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
