Sylwester Nawrocki 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.

Sylwester Nawrocki 1bc515ac6e [media] exynos4-is: Don't overwrite subdevdata in the fimc-is sensor driver
It's an I2C client driver and it must not overwrite the struct v4l2_subdev
dev_priv field, which is used by the v4l2 core to store a pointer to
struct i2c_client.

Sylwester Nawrocki b2afa23669 [media] exynos4-is: Fix regulator/gpio resource releasing on the driver removal
Remove regulator_bulk_free() calls as devm_regulator_bulk_get() function
is used to get the regulators so those will be freed automatically while
the driver is removed.
Missing gpio free is fixed by requesting a gpio with the devm_* API.
All that is done now in the I2C client driver remove() callback is the
media entity cleanup call.

Sylwester Nawrocki 861a51fd40 [media] exynos4-is: Remove redundant MODULE_DEVICE_TABLE entries
Remove unneeded MODULE_DEVICE_TABLE(of,...) instances from files that
are linked into same module. This fixes following error when building
as a module:
LD [M]  drivers/media/platform/exynos4-is/s5p-fimc.o
drivers/media/platform/exynos4-is/fimc-is-sensor.o: In function `.LANCHOR1':

Also remove exporting fimc_is_(un)register_i2c_driver functions, it
is not needed since these functions should be called only from our
module.

Sylwester Nawrocki b8d9834a12 [media] exynos4-is: Add common FIMC-IS image sensor driver
This patch adds a common image sensor driver and Makefile/Kconfig
to enable compilation of the whole IS driver.
The sensor subdev driver currently only handles an image sensor's
power supplies and reset signal. There is no I2C communication as
it is handled by the ISP's firmware.
