[PATCH v2 0/4] ARM: dts: keystone: Add support for new K2G evm

[Franklin S Cooper Jr]

This patchset adds support for new K2G Industrial Communication Engine
evm. For now only a bare minimal dts which will allow ram boot. Additional
peripherals will be added when base K2G SoC patches are upstreamed allowing
peripherals to be enabled.

Version 2 changes:
Make various tweaks to allow unit address to be added to memory node.

  ARM: dts: k2g-evm: Add unit address to memory node

[PATCH v2 1/4] ARM: dts: keystone-k2g: Remove skeleton.dtsi

[Franklin S Cooper Jr]

Adding the unit address to the memory node was causing the below error:
Warning (reg_format): "reg" property in /memory has invalid length
(8 bytes) (#address-cells == 2, #size-cells == 2)

Further debugging showed that this was due to the memory node added by
default to skeleton.dtsi which was being included in keystone-k2g.dtsi.
Adding a missing node was all that was needed to remove this deprecated
dtsi file from the SoC dtsi. With skeleton.dtsi removed the dtc compiler
no longer complained about including the unit address for the memory node.

[PATCH v2 4/4] ARM: dts: keystone: Add minimum support for K2G ICE evm

[Franklin S Cooper Jr]

Add barebones dts support for TI's K2G Industrial Communication Engine evm.
This dts allows the board to boot using a ram based filesystem.

[PATCH v2 2/4] ARM: dts: k2g-evm: Add unit address to memory node

[Franklin S Cooper Jr]

With the new Keystone 2 Industrial Communication EVM adding the
unit address to the memory node it made sense to add it for this board
also.
