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
