+Description:    A sysfs node that used to configures the hardware error
+                isolation method command. The command can be parsed

+                isolated.

What is the "command"?  What is being parsed?  This needs to be
documented a lot more here, this is very vague and not obvious at all.



This command is a string command issued by the user. After the command is configured, the acc driver parses the command.

Are these read-only?  Write only?  read/write?

this node is read-only
