The Tegra AGIC requires two clocks, namely the "ape" (functional) and "apb2ape" (interface) clocks, to operate. Add the compatible string and clock information for the AGIC to the GIC device-tree binding documentation. Signed-off-by: Jon Hunter --- I am not sure if it will be popular to add Tegra specific clock names to the GIC DT docs. However, in that case, then possibly the only alternative is to move the Tegra AGIC driver into its own file and expose the GIC APIs for it to use. Then we could add our own DT doc for the Tegra AGIC as well (based upon the ARM GIC).
