Man page 9 : debugfs_print_regs32

debugfs_print_regs32 - use seq_print to describe a set of registers

int debugfs_print_regs32(struct seq_file *  s , const struct debugfs_reg32 *  regs , int  nregs , void __iomem *  base , char *  prefix );

s
    the seq_file structure being used to generate output

regs
    an array if struct debugfs_reg32 structures

nregs
    the length of the above array

base
    the base address to be used in reading the registers

prefix
    a string to be prefixed to every output line

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
