Subject: [PATCH 8/8] arm64: dts: ti: k3-am642-evm: Remove unnecessary internal pullups for MMC1
Date: Wed, 29 Jul 2026 14:59:58 -0500 [thread overview]
Message-ID: <20260729195958.671147-9-jm@ti.com> (raw)
In-Reply-To: <20260729195958.671147-1-jm@ti.com>
AM64 EVM has external pullups on MMC1 CLK and MMC1 CD pins [0], remove
internal pullups since both enabled results in unnecessary power
consumption.
