[PATCH] dt-bindings: mmc: sunxi: add compatible string for Allwinner A733 MMC0/1/2

From: Jerome Brunet

Date: Fri Jul 31 2026 - 12:51:22 EST


The A733 MMC0/1/2 controllers are compatible with the D1 ones.
Add an A733-specific compatible string, with the D1 as fallback.

Like the A523, the A733 3 first MMC controllers share the same IP block.
The 4th is known to be incompatible with 3 first.

Unlike the A523, the A733 4th controller is not dedicated to eMMC.
This 4th controller access the memory through a different bus. This is not
supported (or tested) yet. It will require a different compatible when the
time comes.
