It is meant to be used within debugfs 16 files based on seq_file that need to show registers, intermixed with other 17 information. The prefix argument may be used to specify a leading string, 18 because some peripherals have several blocks of identical registers, 19 for example configuration of dma channels 20</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="API-debugfs-create-u32-array.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="debugfs.html#debugfs_interface">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="API-debugfs-create-regset32.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top"><span class="phrase">debugfs_create_u32_array</span> </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> <span class="phrase">debugfs_create_regset32</span></td></tr></table></div></body></html> 21
