Subject: [PATCH 2/2] ARM: tegra: Add Tegra30 host1x support
This commit adds the host1x node along with its children to the Tegra30
DTSI. Furthermore the OF auxiliary data table is updated to have proper
names assigned to the platform devices instantiated from the device
tree. Moreover, the clocks required by host1x and the two display
controllers are setup and initialized.
