-+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.
