34947b8aeb [media] exynos4-is: Add the FIMC-IS ISP capture DMA driver
Add a video capture node for the FIMC-IS ISP IP block. The Exynos4x12
FIMC-IS ISP IP block has 2 DMA interfaces that allow to capture raw
Bayer and YUV data to memory.  Currently only the DMA2 output is and
raw Bayer data capture is supported.

d265d9ac6c [media] exynos4-is: Use external s5k6a3 sensor driver
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.

3f823e094b [media] exynos4-is: Simplify fimc-is hardware polling helpers
The fimc_is_hw_wait_intsr0_intsd0() function is currently unused and
can be safely removed. The other polling function simplified and ETIME
error code is replaced with more commonly used ETIMEDOUT.

3263f741e4 [media] exynos4-is: Annotate unused functions
__is_set_init_isp_aa and fimc_is_hw_set_tune currently do not have
any callers. However these functions may be used in the future. Hence
instead of deleting them, staticize and annotate them with __maybe_unused
flag to avoid compiler warnings.

9a761e4368 [media] exynos4-is: Add Exynos4x12 FIMC-IS driver
This patch adds a set of core files of the Exynos4x12 FIMC-IS
V4L2 driver. This includes main functionality like allocating
memory, loading the firmware, FIMC-IS register interface and
host CPU <-> IS command and error code definitions.
The driver currently exposes a single subdev named FIMC-IS-ISP,
which corresponds to the FIMC-IS ISP and DRC IP blocks.
The FIMC-IS-ISP subdev currently supports only a subset of user
controls. For other controls we need several extensions at the
V4L2 API. The supported standard controls are:
brightness, contrast, saturation, hue, sharpness, 3a_lock,
exposure_time_absolute, white_balance_auto_preset,
iso_sensitivity, iso_sensitivity_auto, exposure_metering_mode.
