2013-03-31[media] s5p-fimc: Change the driver directory name to exynos4-isSylwester Nawrocki
The s5p-fimc directory now contains drivers for multiple IP blocks found in multiple Samsung application processors. This includes FIMC (CAMIF), MIPI CSIS and FIMC LITE. FIMC-IS (Imaging Subsystem) driver is going to be put into same directory. Hence we rename it to exynos4-is as s5p-fimc was only relevant for early version of this driver, when it only supported FIMC IP block. The imaging subsystem drivers for Exynos4 SoC series and S5PV210 will be included in drivers/media/platform/exynos4-is directory, with some modules shared with exynos5 series, while the rest of exynos5 specific modules will find their home in drivers/media/platform/exynos5-is.

2013-03-31[media] s5p-fimc: Add device tree support for FIMC device driverSylwester Nawrocki
This patch adds device tree support for FIMC driver on S5PV210 and Exynos4 SoCs. The FIMC IP block's features and quirks encoded statically in the driver are now parsed from the device tree. Once all relevant platforms are converted to device tree based booting the FIMC variant data structures will all be removed from the driver.

2013-03-31[media] s5p-fimc: Use vb2 ioctl/fop helpers in FIMC capture driverSylwester Nawrocki
mmap/poll file operation and several ioctl handlers are replaced with the vb2 helper functions. Some helpers are used indirectly to maintain the buffer queue ownership.

2013-02-05[media] s5p-fimc: Fix bytesperline value for V4L2_PIX_FMT_YUV420M formatSylwester Nawrocki
Make sure bytesperline for Cb, Cr planes for V4L2_PIX_FMT_YUV420M format is half of the Y plane value, rather than having same bytesperline for all planes. While at it, simplify the bytesperline parameter handling by storing it when image format is set and returning those values when getting the format, instead of recalculating bytesperline from intermediate parameters.

2012-12-21[media] s5p-fimc: Add variant data structure for Exynos4x12Sylwester Nawrocki
Add variant data structures for Exynos4212 and Exynos4412 SoC. Add 'const' qualifier for the variant description structures. Also remove has_cam_if flags from FIMC3 on Exynos4210 SoC is it has no interconnections the camera ports.

2012-11-26[media] s5p-fimc: Don't use mutex_lock_interruptible() in device release()Sylwester Nawrocki
Use uninterruptible mutex_lock in the release() file op to make sure all resources are properly freed when a process is being terminated. Returning -ERESTARTSYS has no effect for a terminating process and this caused driver resources not to be released. Not releasing the buffer queue also prevented other drivers to free memory, e.g. in MMAP -> USERPTR scenario. This patch is required for stable kernels v3.6+.
