* clk: samsung: exynos5260: Move struct samsung_cmu_info to init sectionChanwoo Choi2016-09-091-175/+175
| | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the samsung_cmu_info struct instances to initconst section, this decreases the kernel image size by 784 bytes, which makes zImage smaller by 480 bytes. The patch increases .init.rodata section size by 780 bytes but decreases .init.text section size by 1564 bytes. Size of the drivers/clk/samsung/clk-exynos5260.o object file is 29100 bytes without the patch and 28316 after applying the patch. The section size differences are as below: 15c15 < 3 .init.text 000006b8 00000000 00000000 00000034 2**2 --- > 3 .init.text 0000009c 00000000 00000000 00000034 2**2 25c25 < 8 .init.rodata 00003f6c 00000000 00000000 00002f20 2**2 --- > 8 .init.rodata 00004278 00000000 00000000 00002904 2**2 Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>

* clk: samsung: Properly include clk.h and clkdev.hStephen Boyd2015-07-201-2/+0
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | While adding clock support for Exynos5260, the infrastructure to register multiple clock controllers was introduced. Factor out the support for registering multiple clock controller from Exynos5260 clock code to common samsung clock code so that it can be used by other Exynos SoC which have multiple clock controllers.

* clk: samsung: Register clk provider only after registering its all clocksSylwester Nawrocki2014-06-301-0/+2
| | | | | | | | | | 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.
