DEBUGFS_CREATE_REGSE(9)	    The debugfs filesystem     DEBUGFS_CREATE_REGSE(9)

NAME
       debugfs_create_regset32 - create a debugfs file that returns register
       values

SYNOPSIS
       struct dentry * debugfs_create_regset32(const char * name,
					       umode_t mode,
					       struct dentry * parent,
					       struct debugfs_regset32 * regset);

ARGUMENTS
       name
	   a pointer to a string containing the name of the file to create.

       mode
	   the permission that the file should have

       parent
	   a pointer to the parent dentry for this file. This should be a
	   directory dentry if set. If this parameter is NULL, then the file
	   will be created in the root of the debugfs filesystem.

       regset
	   a pointer to a struct debugfs_regset32, which contains a pointer to
	   an array of register definitions, the array size and the base
	   address where the register bank is to be found.

DESCRIPTION
       This function creates a file in debugfs with the given name that
       reports the names and values of a set of 32-bit registers. If the mode
       variable is so set it can be read from. Writing is not supported.

       This function will return a pointer to a dentry if it succeeds. This
       pointer must be passed to the debugfs_remove function when the file is
       to be removed (no automatic cleanup happens if your module is unloaded,
       you are responsible here.) If an error occurs, NULL will be returned.

       If debugfs is not enabled in the kernel, the value -ENODEV will be
       returned. It is not wise to check for this value, but rather, check for
       NULL or !NULL instead as to eliminate the need for #ifdef in the
       calling code.
