[PATCH v3 0/2] Add Axiado AX3000 eMMC Host Controller Support

[PATCH v3 0/2] Add Axiado AX3000 eMMC Host Controller Support

[Tzu-Hao Wei]

Axiado AX3000 SoC eMMC controller is based on Arasan eMMC controller.

This series includes:
1. Add bindings for AX3000 SoC eMMC controller
2. Add arasan sdhci support for eMMC in Axiado AX3000

For platform device tree change, we will send a different series of
patches.

It has been verified on AX3000 platform.

Changes in v3:
- Enable SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN quirk
- Remove dependencies in b4
- Link to v2: https://lore.kernel.org/r/20260109-axiado-ax3000-add-emmc-host-driver-support-v2-0-934f1a61f7c0@axiado.com

Changes in v2:
- Keep host controller changes in this patchset
- Use pdata instead of mix compatible string
- Fix coding style
- Link to v1: https://lore.kernel.org/r/20251222-axiado-ax3000-add-emmc-host-driver-support-v1-0-5457d0ebcdb4@axiado.com
