Subject: ARM: dts: stm32: keep uart4 behavior on stm32mp15xx-dhcom-som
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9269f28b7df5c8067b6e3df387dcf4eaf8b6c211;p=linux.git

ARM: dts: stm32: keep uart4 behavior on stm32mp15xx-dhcom-som

DMA configuration is added to uart nodes in stm32mp15x device tree.
Delete uart4 DMA property in stm32mp15xx-dhcom-som 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").
