[PATCH 6.7 314/713] arm64: dts: imx8mp: Set SPI NOR to max 40 MHz on Data Modul i.MX8M Plus eDM SBC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Marek Vasut <marex@xxxxxxx>

[ 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.
