I see. So there are 2 options: 1. Set the mapping for all 3 sd_emmc_* in the top-most .dtsi Upside: very easy patch Downside: When sd_emmc_a is not enabled "mmc0" will never be available. Might be confusing. 2. Set mapping only for enabled sd_emmc_* in the .dts[i] where it is enabled Upside: Clean setup, only enabled sd_emmc_* have an alias Downside: Much verbose patch(set) Any preferences here? I honestly tend to 1. But this might break boards where sd_emmc_a is not enabled, because the root device _will_ change in that case. Best regards, Alexander
