This patch should bring support for several kernel modules related to I2C to openwrt, which are existing for several years now. Namely there is the i2c-tiny-usb bus driver, to hook up an I2C bus on any device with usb support (prevent voiding warranty when opening and soldering). Second, there is support for the i2c-mux driver and pca954x as a I2C switch driver. Finally there is support for common I2C gpio expander driver modules pca953x and pcf857x. They work without providing platform data recently (can be instantiated at runtime).
