[PATCH v2 4/6] ARM: dts: stm32: add uart nodes on stm32mp13

Tue Mar 28 08:37:21 PDT 2023


Update device-tree stm32mp131.dtsi to add some uart features.

On uart 1, 2, 3, 5, 6, 7, 8 nodes, add compabible, exti interrupts, clock,
reset properties, dma config.

On uart 4 node, only add dma configuration and use exti interrupt.
