Commit Message

Erwan LE RAY Feb. 3, 2022, 5:11 p.m. UTC 
DMA configuration is added to uart nodes in stm32mp15x device tree.
Delete uart4 DMA property in stm32mp15xx-dhcor-avenger96 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 usart2 and uart7 DMA property to keep current behavior.
