This series of patches add support for Tegra114 display, DSI, HDMI, gr2d
and gr3d. Both DSI and HDMI outputs are enabled on Dalmore.
The LVDS panels on Harmony and Cardhu are added to the corresponding DTS
files and support for panels is enabled in the Tegra defconfig.

Add a device node for the MIPI calibration block on Tegra114. There is
no need to disable it by default because it only enables the clock while
performing calibration and therefore shouldn't be consuming any power
when unused.

The binding document
Documentation/devicetree/bindings/gpu/nvidia,tegra20-host1x.txt doesn't
mention an "lp" clock:
- clock-names: Must include the following entries:
- dsi
This MUST be the first entry.
- parent
I assume this is simply an oversight, since this is an obvious extension
of the binding, and that the DT binding will be updated to include that
clock in the list, and hence won't block applying the series because of
this.

Very nice, and it all works and applies without conflicts:-) :-) :-)
Now I must run off and do the panels for Seaboard, Ventana, and the
AC100 sometime.

no need for AC100, I'll submit a patch for it soon. They are already in one of
my testing branches [1].
Thanks

Yes, that was merely an oversight. I've updated the DT binding to
include the lp clock.

Right. Many of the patches I'm carrying locally predate the unit number
requirement change. I did make a pass to update all, but this must have
slipped through the cracks.
Thanks,
