Subject: [PATCH v2 8/9] arm64: dts: qcom: ipq5424-rdp466: Remove eMMC support
Remove eMMC support from the IPQ5424 RDP466 board configuration to
resolve GPIO pin conflicts with SPI NAND interface.
The IPQ5424 RDP466 board is designed with NOR + NAND as the default boot
mode configuration. The eMMC controller and SPI NAND controller share
the same GPIO pins, creating a hardware conflict:
