[PATCH v2 0/6] Device tree updates for host1x support

[PATCH v2 0/6] Device tree updates for host1x support

[Thierry Reding]

This second version of this patch series splits the patches up into more
logical chunks as requested by Stephen. Instead of renaming the matching
parameters in the clock driver, this version renames the AUXDATA entries
to match what the clock driver expects. Furthermore the host1x clock is
initialized to 150 MHz instead of the unsupported 144 MHz.

[PATCH v2 1/6] ARM: tegra: Add Tegra20 host1x support

[Thierry Reding]

Add the host1x node along with its children to the Tegra20 DTSI. Board-
specific DTS files are expected to enable the available outputs and
complement the device tree with data specific to the hardware.

Thanks very much. I have applied the series; DT changes to for-3.8/dt,
and the other changes to for-3.8/soc.

Hi Thierry,

Thank you for your hard work.

On Ventana, LVDS and HDMI worked.
PS: Alex's power sequence patch is needed to enable panel and backlight.
    Also we need to define dc and hdmi nodes in tegra20-ventana.dts.
    We may publish the patches for different boards next.
