This change set adds support for FIMC-LITE devices, available in Exynos4x12 (and Exynos5) SoCs, to the existing s5p-fimc driver. The FIMC-LITE differs from regular FIMC in that it doesn't have a scaler, rotator, color converter and the DMA input. So it's just a basic camera host interface, with additional internal FIFO data output to other SoC sub-modules. Cropping at the host interface input is exposed on a subdev sink pad through the selection API, and composition performed by the output DMA engine can be controlled through selection compose targets on the video node. I tried to make the exynos-fimc-lite module as much independent as possible, to allow its reuse on any other SoCs that have same IP block. This change set also includes small enhancement of V4L2_CID_COLORFX and a patch adding support for this control at the s5p-fimc driver. Changes since first version: - modified V4L2_CID_COLORFX control patches, added V4L2_CID_COLORFX_CBCR control according to suggestions from Hans Verkuil; - fixed VIDIOC_S_FMT ioctl handler so it is now possible to configure random output memory buffer for composition, not only with same resolution as at the subdev's source pad; - corrected completely broken cropping handling at the subdev (looks like someone has forgotten to test it...); - dropped patch 03/13 "s5p-fimc: Simplify..." which was wrong. TODOs: - power management testing (when proper platform support for exynos4x12 is available in the mainline kernel), - complete internal FIFO output support to the internal ISP (should just require filling in the subdev ops stubs); - improve the interrupt handler.
