Viresh, are you going to pick up the other patches, or do you want me to pick them up and send you a pull request? Thanks, Thierry

Applied the other two patches, Thanks.

On Tegra194, data on valid operating points for the CPUs needs to be queried from BPMP. In T194, there is no node representing CPU complex. So, add compatible string to the 'cpus' node instead of using dummy node to bind cpufreq driver. Also, add reference to the BPMP instance for the CPU complex.
