2017-10-16clk: samsung: Add a separate driver for Exynos4412 ISP clocksMarek Szyprowski1-0/+179
Some registers for the Exynos 4412 ISP (Camera subsystem) clocks are located in the ISP power domain. Because those registers are also located in a different memory region than the main clock controller, support for them can be provided by a separate clock controller. This in turn allows to almost seamlessly make it aware of the power domain using recently introduced runtime PM support for clocks.
