clk: samsung: add common clock framework helper functions for Samsung platforms All Samsung platforms include different types of clock including fixed-rate, mux, divider and gate clock types. There are typically hundreds of such clocks on each of the Samsung platforms. To enable Samsung platforms to register these clocks using the common clock framework, a bunch of utility functions are introduced here which simplify the clock registration process. The clocks are usually statically instantiated and registered with common clock framework.

clk: samsung: add infrastructure to register cpu clocks The CPU clock provider supplies the clock to the CPU clock domain. The composition and organization of the CPU clock provider could vary among Exynos SoCs. A CPU clock provider can be composed of clock mux, dividers and gates. This patch defines a new clock type for CPU clock provider and adds infrastructure to register the CPU clock providers for Samsung platforms. Changes by Bartlomiej: - fixed issue with setting lower dividers before the parent clock speed was lowered (the issue resulted in lockup on Exynos4210 SoC based Origen board when "ondemand" cpufreq governor was stress tested) - fixed missing spin_unlock on error in exynos_cpuclk_post_rate_change() problem by moving cfg_data search outside of the spin locked area - removed leftover kfree() in exynos_register_cpu_clock() that could result in dereferencing the NULL pointer on error - moved spin_lock earlier in exynos_cpuclk_pre_rate_change() to cover reading of E4210_SRC_CPU and E4210_DIV_CPU1 registers - added missing "last chance" checks to wait_until_divider_stable() and wait_until_mux_stable() (needed in case that IRQ handling took long time to proceed and resulted in function printing incorrect error message about timeout) - moved E4210_CPU_DIV[0,1]() macros just before their only users, this resulted in moving them from patch #2 to patch #3/6 ("clk: samsung: exynos4: add cpu clock configuration data and instantiate cpu clock") - removed E5250_CPU_DIV[0,1](), E5420_EGL_DIV0() and E5420_KFC_DIV() macros for now - added my Copyrights to drivers/clk/samsung/clk-cpu.c Cc: Tomasz Figa <tomasz.figa@gmail.com> Cc: Mike Turquette <mturquette@linaro.org> Cc: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Signed-off-by: Thomas Abraham <thomas.ab@samsung.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Michael Turquette <mturquette@baylibre.com>

clk: samsung: add clock controller driver for s3c2410, s3c2440 and s3c2442 This driver can handle the clock controllers of the socs mentioned above, as they share a common clock tree with only small differences. 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 pll-rate-tables only the 12mhz variants are currently included. The original code was wrongly checking for 169mhz xti values [a 0 to much at the end], so the original 16mhz pll table would have never been included and its values are so obscure that I have no possibility to at least check their sane-ness. When using the formula from the manual the resulting frequency is near the table value but still slightly off.

So it should most likely be integrated there for dt platforms.
