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

Neither this really.

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

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