Instead of changing dts manually or adding a lot dts files according to different device availability, we provide feature to dynamically update the device node status via command line, then those devices involved with pin conflict can be enabled or disabled dynamically. It's conveniently to use and can save a lot dts board files, also can permenantly fix the pin conflicts issue. The patch series is based on v3.11-rc5.
