[PATCH v4 05/15] arm64: dts: ti: k3-am62a-phycore-som: Set eMMC clock pin as OUTPUT
From: Judith Mendez
Date: Wed Sep 09 2026 - 17:59:03 EST
MMC clock pins must be configured as OUTPUT-only per TRM [0] with
receiver disabled (RXACTIVE bit = 0). Change MMC CLK pins from
PIN_INPUT to PIN_OUTPUT to match documentation.
