Thanks for the clarification.
Patch originated with informal submission by Philipp Zabel:
http://lists.infradead.org/pipermail/linux-arm-kernel/2015-April/337115.html
Update the LVDS0 configuration for imx6qdl-nitrogen6x and imx6qdl-sabrelite
to use simple panel to allow the connection of backlights and simplify the
process of (re)configuring displays.
A U-Boot script to configure the displays based on detection of the
touch controller is available for reference here:
https://github.com/boundarydevices/u-boot-imx6/blob/staging/board/boundary/nitrogen6x/6x_bootscript-mainline.txt
Addition of panel hannstar,hsd100pxn1 is queued for 4.2:

Eric Nelson (2):
ARM: dts: nitrogen6x: use simple-panel instead of display-timings for
LVDS0
ARM: dts: sabrelite: use simple-panel instead of display-timings for
LVDS0
V2 changes commit messages to use proper name of 'label' instead of 'alias'
