[PATCH v2 4/9] ARM: dts: omap: dm816x: refactor and align MMC node

From: Ettore Chimenti

Date: Wed Oct 28 2026 - 12:21:42 EST


From: Andrew Goodbody <andrew.goodbody@xxxxxxxxxx>

Update the MMC node in the TI Sitara DM816x device tree to align with
the structure used in other similar SoCs. The changes include
refactoring the node to better describe the target module and its
sub-nodes.
