Remove the following warnings seen when building with W=1. Warning (unique_unit_address): /soc/timer@40000c00: duplicate unit-address (also used in node /soc/timers@40000c00) This approach is based on some discussions[1], to restructure the dtsi and dts files. Timer5 is enabled by default on stm32f7 series, to act as clockevent. In order to get rid of the W=1 warning, and be compliant with dt-schemas (e.g. dtbs_check): - In stm32f746.dtsi: . Keep the more complete timers5 description . Remove the most simple timer5 node that is duplicate - In each board: . adopt "st,stm32-timer" compatible for timers5, also add the interrupt . use /delete-property/ and /delete-node/ so the it matches the clockevent bindings Note: all this is done in one shot (e.g. not split) to keep clockevent functionality.

Several unused "timer" are duplicate nodes of "timers" nodes. There are two dt-schemas: - timer/st,stm32-timer.yaml: A timer is needed on STM32F7 series, on all boards, to act as clockevent. - mfd/st,stm32-timers.yaml: Timers can be used for other purpose. By default, timer5 is left enabled to be used as clockevent. Remove all other timer clockevent nodes that are currently unused and duplicated. This removes several messages: Warning (unique_unit_address): /soc/timer@.. duplicate unit-address (also used in node /soc/timers@...) Signed-off-by:

Add DMA configuration in stm32mp15x uart nodes by selecting dma direct mode and alternate REQ/ACK dma protocol for uart. DMA direct mode allows to bypass DMA FIFO. Each DMA request immediately initiates a transfer from/to the memory. This allows USART to get data transferred, even when the transfer ends before the DMA FIFO completion. Default REQ/ACK DMA protocol consists in maintaining ACK signal up to the removal of REQuest and the transfer completion. In case of alternative REQ/ACK protocol, ACK de-assertion does not wait the removal of the REQuest, but only the transfer completion. Due to a possible DMA stream lock when transferring data to/from STM32 USART/UART, select this alternative protocol in STM32 USART/UART nodes. Signed-off-by:
