The YAML binding (crypto/atmel,at91sam9g46-aes.yaml) mandates the order
of the channels. Swap them to pass devicetree validation.

Add all the remaining usart nodes for the flexcom block. Although the
DMA channels are specified, DMA is not enabled by default because break
detection doesn't work with DMA.
Keep the nodes disabled by default.

Add all I2C nodes of the flexcom IP blocks. The driver supports
FIFO, DMA or both combined. But the latter isn't working correctly.
Thus, skip the fifo-size property for now. DMA is doing single byte
reads in this case.
Keep the nodes disabled by default.

Add basic support for the Kontron KSwitch D10 MMT. It comes in two
variants: "6G-2GS" which features 6 Gigabit copper ports and two SFP
cages and "8G" which features 6 Gigbabit copper ports (where two are
2.5G capable).
For now the following is supported and working:
- Kernel console
- SFP cages
- SPI
- SGPIO
- Watchdog

Add the MDIO controller nodes. The integrated PHYs are connected to the
second controller. This controller also takes care of the resets of the
integrated PHYs, thus it has two memory regions. The first controller
is routed to the external MDIO/MDC pins.
By default, they are disabled.

Add the switch reset node which will later be used by the switch driver.
The switch reset also resets the GPIO controller and the SGPIO
controller, thus it also has to be connectected to these nodes. This way
the reset will only issued once for the first device requesting the
reset.

Add the SerDes node. On the LAN966x SoC these SerDes are used to connect
network PHYs.
By default, that node is disabled.

I have tested these changes on the lan966x-pcb82891 board which seems to
work fine.

Thanks Claudiu for reviewing and Horatiu for testing.

have the support for our board in mainline to finally get it into
KernelCI.
