Subject: [PATCH 2/8] arm64: dts: ti: k3-am62a: Set MMC clock pins as OUTPUT
Date: Wed, 29 Jul 2026 14:59:52 -0500 [thread overview]
Message-ID: <20260729195958.671147-3-jm@ti.com> (raw)
In-Reply-To: <20260729195958.671147-1-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.
