Instead of duplicating it, each patch moves that part out of the corresponding Colibri iMX7 eMMC overlay into a dtsi shared by the two modules and includes it from both. Only the Atmel MaxTouch wiring, the conflicting PWM channels and the BL_ON pinctrl and GPIO driving the VGA DAC power-save input stay in the SoC specific overlays. The shared files follow the imx6ul-imx6ull-*.dtsi naming already used in the same directory. The first three patches are fixes needed before the rework. Patch 1 (from Emanuele) drives the VGA DAC power-save input through the BL_ON signal, without it the Eval and Aster carrier boards show a black image. Patch 2 adds the Colibri iMX7 eMMC touch adapter and resistive touch .dtbo to dtb-y, as they were built only as a dependency of the combined DTBs and never shipped by dtbs_install. Patch 3 aligns the Colibri iMX6ULL backlight brightness levels with the Colibri iMX7 ones, the LED driver of the 7" displays turns off below roughly 15% duty cycle and only the three highest of the current levels produced a visible image.
