Subject: [PATCH 2/3] arm64: dts: imx8mn-tqma8mqnl: restrict clock for SPI-NOR flash
Date: Tue, 6 Oct 2026 15:25:10 +0200 [thread overview]
Message-ID: <20261006132512.2246196-2-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20261006132512.2246196-1-alexander.stein@ew.tq-group.com>
From: Markus Niebel <Markus.Niebel@ew.tq-group.com>
The FlexSPI controller uses quad SPI with internal clock recovery.
The clock is therefore restricted to 66.666666 MHz according to
data sheet.
