[v1] Add eMMC PHY support for Axiado AX3000 SoC

[PATCH 0/4] Add eMMC PHY support for Axiado AX3000 SoC

Posted by Tzu-Hao Wei 1 month ago

Axiado AX3000 SoC contains Arasan PHY which provides the interface to the
HS200 eMMC controller.

This series includes:
1. Add bindings for Axiado AX3000 eMMC PHY
2. Add Axiado AX3000 eMMC phy driver
3. Update MAINTAINERS for the new driver
4. Update Axiado AX3000 device tree

Changes: (The previous version was mixed with Host driver, so I separate
the PHY driver as a new thread)
- Fix property order in required section to match properties section
- Fixed example to use lowercase hex and proper node naming
- Removed wrapper functions, use readl/writel directly
- Replaced manual polling loops with read_poll_timeout macro
- Used devm_platform_ioremap_resource instead of separate calls
- Removed unnecessary of_match_node check
- Used dev_err_probe for error reporting
- Added proper Kconfig dependencies (ARCH_AXIADO || COMPILE_TEST)
- Fixed various coding style issues
- Link to previous patches: https://lore.kernel.org/all/20251222-axiado-ax3000-add-emmc-host-driver-support-v1-0-5457d0ebcdb4@axiado.com/

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:

Thanks. It will be fixed in the next version.

So v2. Always version your patches correctly.

Hi Krzysztof,

Understood, thanks for clarifying.

Although the PHY patches were split into a separate thread from the
previous combined host+phy series, they are a continuation of the same
work and therefore should follow the existing versioning.

Just to confirm before resending: I will submit the next eMMC PHY series
as v2. Please let me know if this is not correct.

Best regards,
TH
