v5 cover Add eMMC support for Stratix 10 SoCDK

From: Ng Tze Yee <[email protected]>

The first patch adds the device tree binding documentation for the new board compatible string. The second patch introduces a new base device tree include file (socfpga_stratix10_socdk.dtsi) containing common board configurations, and the eMMC-specific device tree file (socfpga_stratix10_socdk_emmc.dts) that includes the base dtsi along with eMMC controller configuration.

This follows a hierarchical structure:
- socfpga_stratix10.dtsi: SoC-level definitions
- socfpga_stratix10_socdk.dtsi: Board-level common configurations
- socfpga_stratix10_socdk_emmc.dts: eMMC daughter board specifics

Changes in v5:
- Move Acked-by's above the Signed-off-by: and remove the empty line between them.
- No code change

Changes in v4:
- Included Acked-by from Rob Herring and Krzysztof Kozlowski in the second patch commit message
- No code change

Changes in v3:
- Refactor socfpga_stratix10_socdk.dts to use the new common dtsi file, eliminating code duplication
- Move gmac2 and i2c2 nodes from socfpga_stratix10_socdk.dtsi to socfpga_stratix10_socdk_emmc.dts as they are specific to the eMMC daughter board variant
- Fix PHY address in socfpga_stratix10_socdk.dts from @0 to @4

Changes in v2:
- Introduced socfpga_stratix10_socdk.dtsi for common board settings
- Updated socfpga_stratix10_socdk_emmc.dts to include the new dtsi
- Added fallback compatible string "altr,socfpga-stratix10-socdk" in the binding documentation for broader compatibility

PATCH v5 1/2 dt-bindings: altera: Add fallback compatible for Stratix 10 SoCDK eMMC variant

From: Ng Tze Yee <[email protected]>

Stratix 10 devkit support a separate eMMC daughter card. Add compatible string for the Stratix 10 SoCDK eMMC daughter board with "altr,socfpga-stratix10-socdk" as a fallback, since this variant is based on the standard SoCDK board.

PATCH v5 2/2 arm64: dts: socfpga: stratix10: Add emmc support

In reply to [email protected]

From: Ng Tze Yee <[email protected]>

The Stratix10 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.

Signed-off-by Ng Tze Yee <[email protected]>

---
Changes in v3:
- Refactored socfpga_stratix10_socdk.dts to use socfpga_stratix10_socdk.dtsi for common board configurations, eliminating code duplication
- Moved gmac2 and i2c2 nodes from socfpga_stratix10_socdk.dtsi back to socfpga_stratix10_socdk_emmc.dts as they are specific to the eMMC daughter board variant and not common to all Stratix 10 SoCDK boards
- Fixed PHY address in socfpga_stratix10_socdk.dts from @0 to @4
