2014-03-14[media] exynos4-is: Use external s5k6a3 sensor driverSylwester Nawrocki
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.

2013-04-25[media] exynos4-is: Don't overwrite subdevdata in the fimc-is sensor driverSylwester Nawrocki
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.

2013-04-25[media] exynos4-is: Fix regulator/gpio resource releasing on the driver removalSylwester Nawrocki
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.

2013-04-25[media] exynos4-is: Remove redundant MODULE_DEVICE_TABLE entriesSylwester Nawrocki
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': fimc-is-sensor.c:(.rodata+0x48): multiple definition of `__mod_of_device_table' drivers/media/platform/exynos4-is/fimc-is.o:fimc-is.c:(.rodata+0x174): first defined here drivers/media/platform/exynos4-is/fimc-is-i2c.o:(.rodata+0x5c): multiple definition of `__mod_of_device_table' drivers/media/platform/exynos4-is/fimc-is.o:fimc-is.c:(.rodata+0x174): first defined here make[4]: *** [drivers/media/platform/exynos4-is/exynos-fimc-is.o] Error 1 Also remove exporting fimc_is_(un)register_i2c_driver functions, it is not needed since these functions should be called only from our module.

2013-04-04[media] exynos4-is: Add common FIMC-IS image sensor driverSylwester Nawrocki
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.
