I don't get how this is related to "Add fixed clock".

Compatible says axg, DTS says T7, so something does not feel right.

You right, I will send a different patch to address that specific issue,
and I will remove it here for v2.

The SOC family is T7, but the emmc is fully compatible with this same
axg code.
I did the same as used in meson-g12-common.dtsi or meson-s4.dtsi, which
use the same compatible.

You still should have a dedicated front compatible (needs documenting in
the binding) expressing full compatibility.

ok, I will use something like that:

compatible = "amlogic,t7-mmc", "amlogic,meson-axg-mmc";
