Subject: [PATCH 2/2] ARM: i.MX8MP: skov: update timing parameters for Samsung RAM
Date: Wed, 15 May 2024 13:20:33 +0200 [thread overview]
Message-ID: <20240515112033.286037-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20240515112033.286037-1-a.fatoum@pengutronix.de>
From: Soren Andersen <san@skov.com>
The RAM is to be operated at a slightly higher data rate of 3200 MT/s,
hence the timings have to be adjusted.
