Subject: [PATCH v1 2/2] arm: dts: k3-am625-verdin: Enable LPDDR4 WDQS control
Date: Wed, 15 May 2024 10:00:58 +0200 [thread overview]
Message-ID: <20240515080058.1530985-3-ghidoliemanuele@gmail.com> (raw)
In-Reply-To: <20240515080058.1530985-1-ghidoliemanuele@gmail.com>
From: Emanuele Ghidoli <emanuele.ghidoli@toradex.com>
Manually, since SysConfig tool do not have the relevant option,
set PHY_LP4_WDQS_OE_EXTEND to 1.
Since WDQS control mode is required on our modules LPDDR4,
this enables WDQS control mode 1.
