From: David Heidelberg <[email protected]> The Pixel 3 features two front-facing Sony IMX355 sensors with different focal lengths (standard and wide-angle).
Both sensors are connected via CSIPHY1 and controlled over CCI I2C1, using MCLK2 as the clock source. Describe the camera nodes and associated resources in the device tree. This enables support for the dual front camera configuration.
