Subject: [PATCH 00/16] ARM: dts: at91: sama5d2: Rework Flexcom definitions

From: Tudor Ambarus <tudor.ambarus@...rochip.com>

Rework the sama5d2 SoC flexcom definitions. The Flexcom IPs are
in the SoC. Move all the flexcom nodes together with their function
definitions in the SoC dtsi. Boards will just fill the pins and enable
the desired functions. With this we remove the duplication of the
flexcom definitions across the sama5d2 boards.

Round the flexcom support and add the missing flexcom definitions.
All the flexcom functions are now defined.

Apart of the aliases and the new flx0 i2c function on sama5d2_xplained,
the only functional change that this patch set adds, is that it uart5,
uart6 and uart7 inherit the atmel,fifo-size = <32>; optional property.
These nodes have both the FIFO size described and the DMA enabled.
uart5 was tested on sama5d27-wlsom1-ek. On uart6 and uart7 a
Bluetooth module can be connected. Tested BT uart7 on sama5d2-icp.
