2015-01-23of: i2c: Add i2c-mux-idle-disconnect DT property to PCA954x mux driverAlexander Sverdlin1-0/+3
Add i2c-mux-idle-disconnect device tree property to PCA954x mux driver. The new property forces the multiplexer to disconnect child buses in idle state. This is used, for example, when there are several multiplexers on the same bus and the devices on the underlying buses might have same I2C addresses.
