2015-07-20clk: samsung: Properly include clk.h and clkdev.hStephen Boyd1-2/+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.

2014-09-22clk: samsung: exynos3250: Register DMC clk providerKrzysztof Kozlowski1-0/+195
Add clock provider for clocks in DMC domain including EPLL and BPLL. The DMC clocks are necessary for Exynos3 devfreq driver. The DMC clock domain uses different address space (0x105C0000) than standard clock domain (0x10030000 - 0x10050000). The difference is huge enough to add new DT node for the clock provider, rather than extending existing address space.

2014-07-26clk: samsung: exynos3250: Enable ARMCLK down featureKrzysztof Kozlowski1-0/+41
Enable ARMCLK down feature on Exynos3250 SoC. The frequency of ARMCLK will be reduced upon entering idle mode (WFI or WFE). The feature behaves like very fast cpufreq ondemand governor. The patch uses simillar settings as Exynos5250 (clk-exynos5250.c), except it disables clock up feature.

2014-06-30clk: samsung: Register clk provider only after registering its all clocksSylwester Nawrocki1-0/+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.

This patch add new the clock drvier of Exynos3250 SoC based on Cortex-A7 using common clock framework. The CMU (Clock Management Unit) of Exynos3250 control PLLs(Phase Locked Loops) and generate system clocks for CPU, buses, and function clocks for individual IPs. The CMU of Exynos3250 includes following clock doamins: - CPU block for Cortex-A7 MPCore processor - LEFTBUS/RIGHTBUS block - TOP block for G3D/MFC/LCD0/ISP/CAM/FSYS/MFC/PERIL/PERIR Signed-off-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Hyunhee Kim <hyunhee.kim@samsung.com> Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Seung-Woo Kim <sw0312.kim@samsung.com> Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Karol Wrona <k.wrona@samsung.com> Signed-off-by: YoungJun Cho <yj44.cho@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: Mike Turquette <mturquette@linaro.org> Cc: Kukjin Kim <kgene.kim@samsung.com> Cc: Rob Herring <robh+dt@kernel.org> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Ian Campbell <ijc+devicetree@hellion.org.uk> Cc: Kumar Gala <galak@codeaurora.org>
