Subject: [PATCH 6.6.y] arm64: dts: ti: k3-am625-sk-common: Set eMMC clock pin as OUTPUT
Date: Tue, 10 Nov 2026 00:52:05 -0500	[thread overview]
Message-ID: <20261110055155.475907-1-sashal@kernel.org> (raw)
In-Reply-To: <20261107053000-failed-6.6-8ef8a0e38d13@kernel.org>

From: Judith Mendez <jm@ti.com>

[ Upstream commit 8ef8a0e38d1377c6d51c06f95c64d87641b2c717 ]

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.
