These file names should be prefixed with exynos5_, since they are FIMC-IS
firmware specific, right ? Also I would spell out full sensor name, e.g.

exynos5_s5k6a3_setfile.bin
exynos5_s5k4e5_setfile.bin

Similar patter is used in the exynos4-is driver.

[PATCH v4 08/13] [media] exynos5-fimc-is: Add sensor interface

2013-08-07 Thread Arun Kumar K
Some sensors to be used with fimc-is are exclusively controlled
by the fimc-is firmware. This minimal sensor driver provides
the required info for the firmware to configure the sensors
sitting on I2C bus.
