Subject[PATCH] ARM: dts: at91: add serial MFD sub-node for usart
Date
The "atmel,at91sam9260-usart" driver is a MFD driver, so it needs sub-nodes
to match the registered platform device. For this reason, we add a serial
subnode to all the "atmel,at91sam9260-usart" serial compatible nods. This
will also remove the boot warning:
"atmel_usart_serial: Failed to locate of_node [id: -2]"
