     12description: |
     13  This binding describes a reset controller device that is used to enable and
     14  disable on-chip peripheral controllers such as USB and SATA, using
     15  "powerdown" control bits found in the STi family SoC system configuration
     16  registers. These have been grouped together into a single reset controller
     17  device for convenience.
     18
     19  The actual action taken when powerdown is asserted is hardware dependent.
     20  However, when asserted it may not be possible to access the hardware's
     21  registers and after an assert/deassert sequence the hardware's previous state
     22  may no longer be valid.
