The slot and switch_rootsysfs driver framework module complies with s3ip sysfs specification (#12893)
Why I did it Provide slot and switch_rootsysfs driver framework that complies with s3ip sysfs specification How I did it 1、 The framework module provides register and unregister interface and implementation. 2、 The framework will help you create the sysfs node How to verify it A demo driver base on this framework will display the sysfs node wich conform to the s3ip sysfs specification
