[PATCH] DTS: MCCMON6: IMX: Provide support for iMX6Q based Liebherr mccmon6 board

[Lukasz Majewski <l.majewski@majess.pl>]

Signed-off-by: Lukasz Majewski <l.majewski@majess.pl>
---
MCCMON6 board support depends on following patches:

1. "video: backlight: pwm_bl: Initialize fb_bl_on[x] and use_count during pwm_backlight_probe()"
	http://patchwork.ozlabs.org/patch/708844/

2. "pwm: imx: Provide atomic operation for IMX PWM driver"
	http://patchwork.ozlabs.org/patch/708847/ - http://patchwork.ozlabs.org/patch/708843/
