Thank you for pointing this out. I agree that the current form is unclear. For v5, I plan to add source labels to the existing flash nodes in aspeed-g6.dtsi: fmc: spi@1e620000 { fmc_flash0: flash@0 { ... }; }; spi2: spi@1e631000 { spi2_flash0: flash@0 { ... }; }; The board DTS will then reference them directly: &fmc_flash0 { ... }; &spi2_flash0 { ... }; This should make the references to the existing nodes explicit. Best, Jacky
