     14  The Clock and Reset (CAR) is the HW module responsible for muxing and gating
     15  Tegra's clocks, and setting their rates. It comprises CLKGEN and RSTGEN units.
     16
     17  CLKGEN provides the registers to program the PLLs. It controls most of
     18  the clock source programming and most of the clock dividers.
     19
     20  CLKGEN input signals include the external clock for the reference frequency
     21  (12 MHz, 26 MHz) and the external clock for the Real Time Clock (32.768 KHz).
     22
     23  Outputs from CLKGEN are inputs clock of the h/w blocks in the Tegra system.
     24
     25  RSTGEN provides the registers needed to control resetting of each block in
     26  the Tegra system.
