Add Agilex eMMC daughter card support
v2 cover Add Agilex eMMC daughter card support
From: Ng Tze Yee <[email protected]>
The Agilex SoCDK supports interchangeable daughter cards for different storage configurations. This series adds support for the eMMC daughter card variant.
The eMMC daughter card is mutually exclusive with the default SDMMC daughter card as it occupies the same physical slot on the SoCDK. Therefore, a separate device tree is required to properly configure the system when using the eMMC variant.
This series:
- Documents the new compatible string for the eMMC daughter card
- Adds a new DTS file based on the existing NAND variant with eMMC- specific MMC controller configuration
Changes in v2:
- Add new compatible string for the eMMC daughter card in the binding file
- Fix space indentation in socfpga_agilex_socdk_emmc.dts
- Fix compatible string in socfpga_agilex_socdk_emmc.dts
- Rephase commit messages for clarity

PATCH v2 2/2 arm64: dts: socfpga: agilex: add emmc support
In reply to [email protected]From: Ng Tze Yee <[email protected]>
The Agilex devkit supports a separate eMMC daughter card. The eMMC daughter card replaces the SDMMC slot that is on the default daughter card and thus requires a separate board dts file.
