++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.
