Merge tag 'fbdev-omap-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux
Pull OMAP fbdev changes from Tomi Valkeinen:
"This is based on the already pulled fbdev-main changes, and this also
merges .dts branch from Tony Lindgren (which has also been pulled), so
that I was able to add the display related .dts changes.
This contains OMAP related fbdev changes for 3.15. The bulk of the
patches are for adding Device Tree support for OMAP Display Subsystem:
- SoCs: OMAP2/3/4
- Boards: OMAP4 Panda, OMAP4 SDP, OMAP3 Beagle, OMAP3 Beagle-xM,
OMAP3 IGEP0020, OMAP3 N900
- Devices: TFP410 Encoder, tpd12s015 HDMI companion chip, Sony
acx565akm panel, MIPI DSI Command mode panel and HDMI, DVI and
Analog TV connectors"
