[PATCH V2 13/14] dt-bindings: arm-gic: Add documentation for Tegra210 AGIC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Tegra AGIC interrupt controller is compatible with the ARM GIC-400
interrupt controller. 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.

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).
