Subject: [PATCH 6/7] arm64: dts: ti: k3-am69-sk: Remove HS400 mode support for eMMC
Date: Thu, 11 Apr 2024 17:52:56 -0500 [thread overview]
Message-ID: <20240411225257.383889-7-jm@ti.com> (raw)
In-Reply-To: <20240411225257.383889-1-jm@ti.com>
From: Dasnavis Sabiya <sabiya.d@ti.com>
The eMMC fails to enumerate intermittently on HS400 mode. Also
observing multiple CQE recovery warnings.
Update the sdhci0 node to disable HS400 and set HS200 mode for
eMMC node.
