Subject: mfd: at91-usart: Do not use compatible to register child devices
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4c5840b909f3a12fc5f1275024d0cff6fd23235f;p=linux.git

mfd: at91-usart: Do not use compatible to register child devices

There are no separate serial/SPI devices under the at91-usart MFD, but
actually the MFD is used as a serial or a SPI device. There are no DT
sub-nodes for the MFD children, so we should use platform device API to
register the drivers.
