Subject: [PATCH] ARM: dts: microchip: sam9x7: Add missing usart-mode property
Add the atmel,usart-mode property to UART nodes in Microchip SAM9X75
boards' device trees (boards which inherit sam9x7.dtsi). This ensures
compliance with the atmel at91-usart.yaml schema and resolves errors
that occur during DT validation, such as:
arch/arm/boot/dts/microchip/at91-sam9x75_curiosity.dtb: serial@200:
serial@...' does not match '^spi(@.*|-([0-9]|[1-9][0-9]+))?$'
from schema: http://devicetree.org/schemas/serial/atmel,at91-usart.yaml#
arch/arm/boot/dts/microchip/at91-sam9x75_curiosity.dtb:
serial@200: atmel,use-dma-rx: False schema does not allow True
from schema: http://devicetree.org/schemas/serial/atmel,at91-usart.yaml#
arch/arm/boot/dts/microchip/at91-sam9x75_curiosity.dtb:
serial@200: atmel,fifo-size: False schema does not allow 16
from schema: http://devicetree.org/schemas/serial/atmel,at91-usart.yaml#
By adding "atmel,usart-mode = <AT91_USART_MODE_SERIAL>" to UART nodes
0 up until 12, these errors are resolved, ensuring proper DTB validation.
This issue has been tested on the sam9x75 (sam9x75eb & sam9x75_curiosity)
boards, both of which inherit the sam9x7.dtsi file.
