[RFC] drm/exynos: add FIMC driver

From: Eunchul Kim chulspro.kim@samsung.com

FIMC supports image scaler/rotator and input/output DMA operations This FIMC driver is exynos drm specific and supports General Scaler (version 5.1) of later Exynos series from Exynos4X12 and this patch is just for RFC.

The FIMC is performed by three tasks simply. 1. Set property about source, destination 2. Buffer managements about source, destination 3. Start various operations

The FIMC drivers supports Memory to Memory operations with various converting. User can make converted image using this driver.

And supports various operations - Scale operation generates various sizes of image. - CSC(Color space conversion) operation supports format converting from YUV to RGB, vise versa. - Rotate operation supports to 90, 180, 270 degree. - Writeback operation generates cloned image from display controller(FIMD) and supports image effect functions. - Input DMA reads image data from the memory. - Output DMA writes image data to memory. - Crop operation supports cutting the image.

User should make property informations and set this property to registers. The Exynos FIMC driver manages input/output DMA with various operations. Some registers needs memory base address(physical address) of image. User doesn't know its physical address, so fills the gem handle of that memory than address of image base, then FIMC driver converts it to DMA address.

We adds three ioctls and one event for Exynos FIMC Basic control flow is same as below Set Source/Destination property -> Create gem handle -> Set buffer register -> Start control about operations -> Event ouccured to User -> User handle converted image -> Add unused buffer -> Free gem handle -> Stop control about operations

- ioctls DRM_EXYNOS_FIMC_PROPERTY: set/get format, position, rotation, flip about source/destination DRM_EXYNOS_FIMC_BUF: alloc/free buffer and make event list DRM_EXYNOS_FIMC_CTRL: start/stop control operations

- events DRM_EXYNOS_FIMC_EVENT: event to give notification completion of buffer DMA with buffer list
