From: Lukasz Majewski <l.majewski@xxxxxxxxx> This patch provides support for Liebherr's Monitor 6 board (abverrated as mccmon6) to Linux kernel. Signed-off-by: Lukasz Majewski <lukma@xxxxxxx> --- 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/ --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/imx6q-mccmon6.dts | 477 ++++++++++++++++++++++++++++++++++++ 2 files changed, 478 insertions(+) create mode 100644 arch/arm/boot/dts/imx6q-mccmon6.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index c558ba7..0aa8e89 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -383,6 +383,7 @@ dtb-$(CONFIG_SOC_IMX6Q) += \ imx6q-hummingboard.dtb \ imx6q-icore-rqs.dtb \ imx6q-marsboard.dtb \ + imx6q-mccmon6.dtb \ imx6q-nitrogen6x.dtb \ imx6q-nitrogen6_max.dtb \ imx6q-novena.dtb \ diff --git a/arch/arm/boot/dts/imx6q-mccmon6.dts b/arch/arm/boot/dts/imx6q-mccmon6.dts new file mode 100644 index 0000000..7128dc2 --- /dev/null +++ b/arch/arm/boot/dts/imx6q-mccmon6.dts @@ -0,0 +1,477 @@ +/* + * Copyright 2016-2017 + * Lukasz Majewski, DENX Software Engineering, lukma@xxxxxxx + * + * This program is free software;
