[PATCH 00/10] ARM: tegra: DSI and panel support

[Thierry Reding]

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.

[PATCH 03/10] ARM: tegra: Add MIPI calibration DT entries for Tegra114

[Thierry Reding]

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.

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.

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.

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

[PATCH 09/10] ARM: tegra: Enable HDMI support on Dalmore

[Thierry Reding]

From: Mikko Perttunen <mperttunen-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Add HDMI node to the Dalmore device tree and hook up the VDD and PLL
regulators as well as the I2C adapter used for DDC and the GPIO used
for hotplug detection.

Very nice, and it all works and applies without conflicts:-) :-) :-)
