   This function outputs a text block describing the current values of
   some 32-bit hardware registers. It is meant to be used within debugfs
   files based on seq_file that need to show registers, intermixed with other
   information. The prefix argument may be used to specify a leading string,
   because some peripherals have several blocks of identical registers,
   for example configuration of dma channels
