18c2ecf20Sopenharmony_ciNVIDIA Tegra Activity Monitor 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciThe activity monitor block collects statistics about the behaviour of other 48c2ecf20Sopenharmony_cicomponents in the system. This information can be used to derive the rate at 58c2ecf20Sopenharmony_ciwhich the external memory needs to be clocked in order to serve all requests 68c2ecf20Sopenharmony_cifrom the monitored clients. 78c2ecf20Sopenharmony_ci 88c2ecf20Sopenharmony_ciRequired properties: 98c2ecf20Sopenharmony_ci- compatible: should be "nvidia,tegra<chip>-actmon" 108c2ecf20Sopenharmony_ci- reg: offset and length of the register set for the device 118c2ecf20Sopenharmony_ci- interrupts: standard interrupt property 128c2ecf20Sopenharmony_ci- clocks: Must contain a phandle and clock specifier pair for each entry in 138c2ecf20Sopenharmony_ciclock-names.
