This makes it seem like stratix10-socdk should be a fallback for this
emmc device, if the new compatible only describes the combination
device.

Hi Conor,

Just to confirm I understand correctly, would you like me to update both:

1. The binding schema (altera.yaml) to split the Stratix 10 boards into 
two patterns, with the eMMC variant having a fallback chain?

       - description: Stratix 10 boards
         items:
           - enum:
               - altr,socfpga-stratix10-socdk
               - altr,socfpga-stratix10-swvp
           - const: altr,socfpga-stratix10

       - description: Stratix 10 SoCDK eMMC variant
         items:
           - const: altr,socfpga-stratix10-socdk-emmc
           - const: altr,socfpga-stratix10-socdk
           - const: altr,socfpga-stratix10

2. The device tree (socfpga_stratix10_socdk_emmc.dts) to update the 
compatible property

from:
compatible = "altr,socfpga-stratix10-socdk-emmc", "altr,socfpga-stratix10";

to:
compatible = "altr,socfpga-stratix10-socdk-emmc",
"altr,socfpga-stratix10-socdk",
"altr,socfpga-stratix10";

Please let me know if this is the expected approach, or if you had 
something different in mind.

Yes, that's effectively what I had in mind.
