12 description: |-
13 IMX258 is a diagonal 5.867mm (Type 1/3.06) 13 Mega-pixel CMOS active pixel
14 type stacked image sensor with a square pixel array of size 4208 x 3120. It
15 is programmable through I2C interface. Image data is sent through MIPI
16 CSI-2. The sensor exists in two different models, a standard variant
17 (IMX258) and a variant with phase detection autofocus (IMX258-PDAF).
18 The camera module does not expose the model through registers, so the
19 exact model needs to be specified.
