This patch removes the common fimc-is-sensor driver for image sensors that are normally controlled by the FIMC-IS firmware. The FIMC-IS driver now contains only a table of properties specific to each sensor. The sensor properties required for the ISP's firmware are parsed from device tree and retrieved from the internal table, which is selected based on the compatible property of an image sensor. To use the Exynos4x12 internal ISP the S5K6A3 sensor driver (drivers/ media/i2c/s5k6a3.c) is now required.
