Subject: [PATCH v4 08/15] arm64: dts: ti: k3-am625-beagleplay: Set MMC clock pins as OUTPUT
Date: Wed, 9 Sep 2026 16:47:36 -0500	[thread overview]
Message-ID: <20260909214743.899477-9-jm@ti.com> (raw)
In-Reply-To: <20260909214743.899477-1-jm@ti.com>

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.
