This series introduces support for the DFLL as a CPU clock source on Tegra210. As Jetson TX2 uses a PWM controlled regulator IC which is driven directly by the DFLLs PWM output, we also introduce support for PWM regulators next to I2C controlled regulators. The DFLL output frequency is directly controlled by the regulator voltage. The registers for controlling the PWM are part of the DFLL IP block, so there's no separate linux regulator object involved because the regulator IC only supplies the rail powering the DFLL and the CPUs. It doesn't have any other controls.
