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).
