This patch series is an initial version of a driver for the camera ISP subsystem (FIMC-IS) embedded in Samsung Exynos4x12 SoCs. The FIMC-IS subsystem is build around a ARM Cortex-A5 CPU that controls its dedicated peripherals, like I2C, SPI, UART, PWM, ADC,... and the ISP chain. There are 3 hardware image processing blocks: ISP, DRC (dynamic range compression) and FD (face detection) that are normally controlled by the Cortex-A5 firmware. The driver currently exposes two additional sub-device to user space: the image sensor and FIMC-IS-ISP sub-device. Another one might be added in future for the FD features. The FIMC-IS has various data inputs, it can capture data from memory or from other SoC IP blocks (FIMC-LITE). It is currently plugged between FIMC-LITE and FIMC IP blocks, so there is a media pipeline like: sensor -> MIPI-CSIS -> FIMC-LITE -> FIMC-IS-ISP -> FIMC -> memory A raw Bayer image data can be captured from the ISP block which has it's own DMA engines. Support for this is not really included in this series though, only a video capture node driver stubs are added. This is a bit complicated code, nevertheless I would really appreciate any review comments you might have. And this is just a basic set of futures this patch series addresses. Others include input/output DMA support for the DRC and FD blocks, support for more ISP controls, etc. But it all is not immediately needed to make use of this really great ISP!
