[PATCH] ARM: dts: warp: Add initial WaRP Board support

Otavio Salvador
2015-02-25T17:02:37Z

The WaRP Board is a Wearable Reference Plaform. The board features:

- Freescale i.MX6 SoloLite processor with 512MB of RAM
- Freescale FXOS8700CQ 6-axis Xtrinsic sensor
- Freescale Kinetis KL16 MCU
- Freescale Xtrinsic MMA955xL intelligent motion sensing platform

The board implements a hybrid architecture to address the evolving
needs of the wearables market. The platform consists of a main board
and an example daughtercard with the ability to add additional
daughtercards for different usage models.
