Subject: [PATCH v3 2/4] arm64: dts: ti: k3-am62a: Set MMC clock pins as OUTPUT
Date: Wed, 5 Aug 2026 17:54:36 -0500 [thread overview]
Message-ID: <20260805225438.464184-3-jm@ti.com> (raw)
In-Reply-To: <20260805225438.464184-1-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.
