clk: samsung: exynos3250: Add clocks using common clock framework
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>
