From 49bc295c6a5321f4856bc7cf45c68dbe87e76bc9 Mon Sep 17 00:00:00 2001 From: Erwan Le Ray Date: Thu, 3 Feb 2022 18:11:04 +0100 Subject: [PATCH] ARM: dts: stm32: keep uart4 behavior on stm32mp157a-iot-box DMA configuration is added to uart nodes in stm32mp15x device tree. Delete uart4 DMA property in stm32mp157a-iot-box board device tree to keep console in irq mode, as DMA support for console has been removed from the driver by commit e359b4411c28 ("serial: stm32: fix threaded interrupt handling").
