From a48006fe4ce7866d4f1891052eb2a81a30207f8e Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 17 Feb 2024 22:33:30 +0100 Subject: [PATCH] arm64: dts: imx8mp: Set SPI NOR to max 40 MHz on Data Modul i.MX8M Plus eDM SBC [ Upstream commit 13ab6f174a6b577bd7d09124b47ec8ace2682e42 ] The SPI NOR bus routing on this board cannot go above 50 MHz, set the clock frequency to maximum of 40 MHz to be within a safe margin. Remove the comment as well.
