[PATCH v2 2/2] ARM: dts: imx6q: Add mccmon6 board support

Lukasz Majewski lukma at denx.de
Mon Jan 2 15:43:38 PST 2017


From: Lukasz Majewski <l.majewski at majess.pl>

This patch provides support for Liebherr's Monitor 6 board (abverrated as
mccmon6) to Linux kernel.

Signed-off-by: Lukasz Majewski <lukma at denx.de>
---
Changes for v2:
- Reorganize the dts file according to Valdimir Zapolskiy's comments

---
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/
