2016-03-03clk: samsung: Remove CLK_IS_ROOTStephen Boyd
This flag is a no-op now. Remove usage of the flag. Acked-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2015-07-20clk: samsung: Properly include clk.h and clkdev.hStephen Boyd
Clock provider drivers generally shouldn't include clk.h because it's the consumer API. Only include clk.h in files that are using it. The clkdev.h header isn't always used either, so remove it and add in slab.h where files were relying on it to include slab for them.

2014-10-01clk: samsung: register restart handlers for s3c2412 and s3c2443Heiko Stübner
S3C2412, S3C2443 and their derivatives contain a special software-reset register in their system-controller. Therefore register a restart handler for those. Tested on a s3c2416-based board, s3c2412 compile-tested. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-06-30clk: samsung: Register clk provider only after registering its all clocksSylwester Nawrocki
Ensure the clock provider is not registered until after all its related clocks were created and are ready to use. Currently there are races possible and any (of_)clk_get() call right after a clock provider's clk_init_cb callback call may fail.

2014-05-14clk/samsung: add support for multiple clock providersRahul Sharma
Samsung CCF helper functions do not provide support to register multiple Clock Providers for a given SoC. Due to this limitation, SoC platforms are not able to use these helpers for registering multiple clock providers and are forced to bypass this layer. This layer is modified accordingly to enable the support for multiple clock providers. Clock file for exynos4, exynos5250, exynos5420, exynos5440, S3c64xx, S3c24xx are also modified as per changed helper functions.

2014-04-14clk: samsung: add clock-driver for s3c2416, s3c2443 and s3c2450Heiko Stuebner
The three SoCs share a common clock tree which only differs in the existence of some special clocks. As with all parts common to these three SoCs the driver is named after the s3c2443, as it was the first SoC introducing this structure and there exists no other label to describe this s3c24xx epoch. The clock structure is built according to the manuals of the included SoCs and might include changes in comparison to the previous clock structure. As an example the sclk_uart gate was never handled previously and the div_uart was made to be the clock used by the serial driver.
