Subject: [PATCH v2 00/10] Add support for the Axis ARTPEC-8 SoC
Add basic support for the Axis ARTPEC-8 SoC which contains
quad-core Cortex-A53 CPU and other several IPs. This SoC is an
Axis-designed chipset used in surveillance camera products such as
the AXIS Q1656-LE and AXIS Q3538-LVE.
This ARTPEC-8 SoC has a variety of Samsung-specific IP blocks and
Axis-specific IP blocks and SoC is manufactured by Samsung Foundry.
List of Samsung-provided IPs:
- UART
- Ethernet (Vendor: Synopsys)
- SDIO
- SPI
- HSI2C
- I2S
- CMU (Clock Management Unit)
- Pinctrl (GPIO)
- PCIe (Vendor: Synopsys)
- USB (Vendor: Synopsys)
List of Axis-provided IPs:
- VIP (Image Sensor Processing IP)
- VPP (Video Post Processing)
- GPU
- CDC (Video Encoder)
This patch series includes below changes:
- CMU (Clock Management Unit) driver and its bindings
- GPIO pinctrl configuration and its bindings
- Basic Device Tree for ARTPEC-8 SoC and boards
The patch series has been tested on the ARTPEC-8 EVB with
Linux v6.15-rc5 and intended to be merged via the `arm-soc` tree.
---
Changes in v2:
- Update SoB sections in all patches
- Update the copyright year to 2025
- Add CMU abbreviation description
- Merge dt-bindings patch 01 and 02 into single patch
- Modify yaml file to fit coding style in CMU
- Modify clock-names
- Reorder config macros to fit coding style
- Remove the unused macro in clock driver code
- Squash all clock driver patches (4 to 10) into single patch
- Split yaml conversion patch translation and add ARTPEC-8 SoC
- Remove "clock-frequency" property from cpu node in dtsi
- Remove the "status" property in dts and dtsi
- Reorder the DTS and pin nodes to follow the alphabetical and DTS coding style
- Change items property in axis.yaml
- Move dts files to exynos folder
- Removed ARCH_ARTPEC8 from platform Kconfig
- Add pattern in MAINTAINER file
- Merge dtsi and pinctrl dtsi file
- Split board dts file
Link to v1: https://lore.kernel.org/all/20250710002047.1573841-1-ksk4725@coasia.com/
NOTE: The first version has been sent by Coasia.
After that, it has been agreed between Coasia and Samsung that Samsung will take
ownership of upstreaming ARTPEC-8 and ARTPEC-9 platforms.
