[PATCH v4 00/10] Add minimal Exynos8895 SoC and SM-G950F support

[PATCH v4 00/10] Add minimal Exynos8895 SoC and SM-G950F support

[Ivaylo Ivanov]

Hi folks,

This series adds initial SoC support for the Exynos 8895 SoC and also
initial board support for Samsung Galaxy S8 phone (SM-G950F), codenamed
dreamlte.

The Exynos 8895 SoC is also used in S8 Plus (dream2lte), Note 8 (greatlte)
and Meizu 15 Plus (m1891). Currently DT is added for the Exynos 8895 SoC
and dreamlte, but it should be really easy to adapt for the other devices
with the same SoC. It has been tested with dtbs_check W=1 and results
in no warnings.

The support added in this series consists of:
* cpus
* pinctrl
* gpio
* simple-framebuffer
* pstore

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

The preferred way to boot this device is by using a small shim bl called
uniLoader [1], which packages the mainline kernel and DT and jumps to
the kernel. This is done in order to work around some issues caused by
the stock, and non-replacable Samsung S-Boot bootloader. For example,
S-Boot leaves the decon trigger control unset, which causes the framebuffer
to not refresh.

Changes in v2:
- No patch changes were made, only fixed the issues with my git send-email

Changes in v3:
- Added a-b tags by Rob Herring and Linus Walleij
- Ordered the Samsung Mongoose M2 compatible in cpus.yaml
- Ordered the EXYNOS8895 information in exynos-chipid.c
- Made the commit message for pinctrl support more detailed
- Made the commit message for exynos-pmu.yaml more detailed
- Fixed suffixes for the exynos8895 pinctrl device tree
- Removed redundant nodes from the exynos8895 pinctrl device tree
- Made the arm-a53-pmu node cover only the Cortex A53 cores
- Added a comment mentioning the lack of a PMU model for Mongoose cores
- Added a comment mentioning the issue with CNTFRQ_EL0
- Removed the redundant fixed rate clocks wrapper
- Ordered the nodes by the DTS coding style in all 8895 DT files
- Removed the redundant status property from the simple-framebuffer node
- Switch to dual licensing (GPL-2.0 OR BSD-3-Clause) for the DT files

Changes in v4:
- Added r-b tag by Sam Protsenko
- Resolved the remaining pinctrl node name regex issues
- Corrected interrupt-cells for gpa1-gpio-bank
- Fixed suffixes for the dreamlte gpio keys pin nodes
- Reordered the dreamlte gpio-keys nodes alphabetically
- Fixed interrupt-controller simple-bus unit address
- Change framebuffer-related node labels to match other device trees

Kind regards,

Ivaylo.

[PATCH v4 07/10] dt-bindings: soc: samsung: exynos-pmu: Add exynos8895 compatible

[Ivaylo Ivanov]

Add exynos8895-pmu compatible to the bindings documentation. Since
Samsung, as usual, reuses devices from older designs, use the
samsung,exynos7-pmu compatible.

[PATCH v4 08/10] arm64: dts: exynos: Add initial support for exynos8895 SoC

[Ivaylo Ivanov]

Exynos 8895 SoC is an ARMv8 mobile SoC found in the Samsung Galaxy
S8 (dreamlte), S8 Plus (dream2lte), Note 8 (greatlte) and the Meizu
15 Plus (m1891). Add minimal support for that SoC, including:

- All 8 cores via PSCI
- ChipID
- Generic ARMV8 Timer
- Enumarate all pinctrl nodes

The devices using this SoC suffer from an issue caused by the stock
Samsung bootloader, as it doesn't configure CNTFRQ_EL0. Hence it's
needed to hardcode the adequate frequency in the timer node,
otherwise the kernel panics.

Further platform support will be added over time.

[PATCH v4 10/10] arm64: dts: exynos: Add initial support for Samsung Galaxy S8

[Ivaylo Ivanov]

Samsung Galaxy S8 (SM-G950F), codenamed dreamlte, is a mobile phone
from 2017. It features 4GB RAM, 64GB UFS 2.1, Exynos 8895 SoC and a
1440x2960 Super AMOLED display.

This initial device tree enables SimpleFB, PSTORE and GPIO keys.

Why cpu@0 is cpu4 not cpu0? Anyway, these should be ordered by unit
address.

ranges is the second property (see DTS coding style).

cpu@100 is the boot core of the first cluster consisting of cortex-a53

cores, hence why it's labelled as cpu0. The second cluster contains

the Mongoose cores, labelled and ordered after the first cluster.


It's ordered like so on a lot of SoCs for sanity's sake, hence why I

believe it should stay like that.


If you still think that they must be ordered by unit address, please

explicitly let me know so that I include that change in the v5.

I tend to switch to style expressed in DTS coding style, especially that
we might use at some point sorting tool which would then need exception
for CPUs. Keep existing labels, assuming they reflect reality, but order
by unit address.
