+description:
+  The Galaxy Core GC2145 is a 2 Megapixel CMOS image sensor, for mobile
+  phone camera applications and digital camera products. GC2145 incorporates a
+  1616V x 1232H active pixel array, on-chip 10-bit ADC, and image signal
+  processor allowing AE/AWB/interpolation/de-noise/color-conversion and
+  gamma correction. Bayer RGB, RGB565 and YCbCr 4:2:2 can be provided by the
+  sensor. It is programmable through an I2C interface. Image data is sent
+  either through a parallel interface or through MIPI CSI-2.
