[PATCH 0/2] ARM: dts: use simple-panel for nitrogen6x and sabrelite

[Eric Nelson]

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:

[PATCH V2 0/2] ARM: dts: use simple-panel for nitrogen6x and sabrelite

[Eric Nelson]

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:

The fsl,data-width property shouldn't be needed anymore if you
set .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG for the hsd100pxn1
panel in panel-simple.c.

Thanks again Philipp.

That's a much better place to put it, since this is a panel feature,
not a feature of the LVDS channel.

Are you planning to submit a patch to panel-simple.c for this?

Because of the dependency, I'd like to handle this in a separate
patch instead of V3 of this patch set.

Please advise,


Eric

Done.

I agree, it's better to remove this in a separate step after the panel
driver is merged.
