The Tegra AGIC is an interrupt controller that is compatible with the ARM GIC-400, however, it is a 2nd level controller and requires runtime power-management because it is outside the main CPU complex. Ideally, the AGIC would use the existing "arm,gic-400" compatibility string, but because of the power management requirements it cannot be initialised early and is initialised by a platform driver. Therefore, to distinguish between the Tegra AGIC and a normal GIC-400, and to ensure that the appropriate driver initialises the AGIC, add the compatible string and clock information for the AGIC to the GIC device-tree binding documentation.
