[PATCH v1 0/3] clk: tegra: add DFLL support for Tegra 4

[Svyatoslav Ryhel]

DFLL is a dedicated clock source for the Fast CPU. The DFLL is based on
a ring oscillator and translates voltage changes into frequency
compensation changes needed to prevent the CPU from failing and is
essential for correct CPU frequency scaling.
