[PATCH 6/8] arm64: dts: ti: k3-am64: Let MMC1 clock loopback use hardware default
From: Judith Mendez
Date: Wed Jul 29 2026 - 16:04:03 EST
Clock loopback (CLKLB) should not be changed from its default state.
Explicit pinmux config is unnecessary and overrides correct default.
Drop CLKLB in pinmux node for MMC1.
