++Name:   imx219
++Info:   Sony IMX219 camera module.
++        Uses Unicam 1, which is the standard camera connector on most Pi
++        variants.
++Load:   dtoverlay=imx219,<param>=<val>
++Params: i2c_pins_0_1            Use pins 0&1 for the I2C instead of 44&45.
++                                Useful on Compute Modules.
++
++        i2c_pins_28_29          Use pins 28&29 for the I2C instead of 44&45.
++                                This is required for Pi B+, 2, 0, and 0W.
