 The CAR (Clock And Reset) Controller on Tegra is the HW module responsible

   In clock consumers, this cell represents the clock ID exposed by the CAR.

-  registers. These IDs often match those in the CAR's RST_DEVICES registers,
-  but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
