[RFC PATCH] ARM: dts: Add support for Turris Omnia

From: Tomas Hlavacek
Date: Tue Nov 22 2016 - 19:10:09 EST

Turris Omnia board by CZ.NIC:

* Marvell Armada 385 SoC
* 1 or 2 GB DDR3
* eMMC
* 8 MB SPI flash (U-Boot and rescue Linux image)
* 88E1514 PHY
* 88E6176 Ethernet switch (not supported)

Supported board revision: CZ11NIC13 (production board).

Signed-off-by: Tomas Hlavacek <tmshlvck@xxxxxxxxx>

Changes since Uwe's version:

- add MBUS regions (needed for Marvell CESA)
- remove rtc disable (WFM with CZ11NIC13 = production board)
- cleanup comments

Unsupported peripherals:
- MV88E7176 switch
- SFP
- LEDs
