This patch series is a refactoring of the exynos4-is driver to get rid of the common fimc-is-sensor driver and to adapt it to use "standard" sensor subdev drivers, one per each image sensor type. Then a clock provider is added to the exynos4-is driver and the s5k6a3 subdev is modified to use one of the clocks registered by exynos4-is.
Arun, I think you could reuse the s5k6a3 sensor for your work on the Exynos5 FIMC-IS driver. One advantage of separate sensor drivers is that the power on/off sequences can be written specifically for each sensor. We are probably going to need such sequences per board in future. Also having the clock control inside the sensor subdev allows to better match the hardware power on/off sequence requirements, however the S5K6A3 sensor can have active clock signal on its clock input pin even when all its power supplies are turned off. I'm posting this series before having a proper implementation for clk_unregister() in the clock framework, so you are not blocked with your Exynos5 FIMC-IS works.
