This is the second version of driver. I added a mfd driver which by
default probes atmel_serial driver and if in dt is specified to probe
the spi driver, then the spi-at91-usart driver will be probed. The
compatible for atmel_serial is now the compatible for at91-usart mfd
driver and compatilbe for atmel_serial driver was changed in order to
keep the bindings for serial as they are.

Changes in v10:
-fixed kbuild test robot warning

Changes in v9:
- minor changes
- rebased on top of broonie/for-4.19

Changes in v8:
- fixed passing an empty mfd cell if "atmel,usart-mode" value is invalid

Changes in v7:
- synced up  SPDIX license with module license
- numbering of usart modes starts from 0 insteand of 1

Changes in v6:
- removed unused compatible strings from serial and spi drivers

Changes in v5:
- fixed usage of stdout-path property with atmel_serial driver

Changes in v4:
- modified the spi driver to use cs gpio support form spi subsystem
- fixed dma transfers for serial driver
- squashed binding for spi and serial and moved them to mfd/atmel-usart.txt

Changes in v3:
- fixed spi slaves probing

Changes in v2:
- added at91-usart mfd driver
- modified spi-at91-usart driver to work as mfd driver child
- modified atmel_serial driver to work as mfd driver child

Changes in v1:
- added spi-at91-usart driver

Radu Pirea (6):
   MAINTAINERS: add at91 usart mfd driver
   dt-bindings: add binding for atmel-usart in SPI mode
   mfd: at91-usart: added mfd driver for usart
   MAINTAINERS: add at91 usart spi driver
   spi: at91-usart: add driver for at91-usart as spi
   tty/serial: atmel: change the driver to work under at91-usart mfd

For the record or if needed by the MAINTAINERS changes, you can add my:
Acked-by: Nicolas Ferre <nicolas.fe...@microchip.com>
for the whole series.

Once the remarks by Mark are addressed, you can certainly re-send the series with all tags collected for Lee to take it, if he is okay with this process, of course...

Thanks, best regards,
