From ab0e8febe59feefb5e190a28c805277735fc1bda Mon Sep 17 00:00:00 2001 From: Erwan Le Ray Date: Thu, 3 Feb 2022 18:11:05 +0100 Subject: [PATCH] ARM: dts: stm32: keep uart nodes behavior on stm32mp1-microdev2.0-of7 DMA configuration is added to uart nodes in stm32mp15x device tree. Delete uart4 DMA property in stm32mp1-microdev2.0-of7 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"). Delete also uart8 DMA property to keep current behavior.
