[PATCH 1/2] ARM: dts: mx6: Add support for mx6q nitrogen board

[PATCH 1/2] ARM: dts: mx6: Add support for mx6q nitrogen board

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

mx6q sabrelite and nitrogen boards are hardware compatible.

Boundary Devices have a line of nitrogen boards based on quad/dual-lite and solo
variants.

Let's consolidate the common peripheral nodes into imx6qdl-nitrogen.dtsi and
add support for the mx6 quad nitrogen board.
