We meet some boards having a lot of pin conflicts between different devices, only one of them can be enabled to run at one time.
e.g. imx6q sabreauto board, i2c, spi, weim, flexcan, uart and etc involved with pin conflict.
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.
