clk: samsung: exynos4: add cpu clock configuration data and instantiate cpu clock
With the addition of the new Samsung specific cpu-clock type, the arm clock can be represented as a cpu-clock type. Add the CPU clock configuration data and instantiate the CPU clock type for Exynos4210. Changes by Bartlomiej: - fixed issue with wrong dividers being setup by Common Clock Framework (by an addition of CLK_RECALC_NEW_RATES clock flag to mout_apll clock, without this change cpufreq-dt driver showed ~10 mA larger energy consumption when compared to cpufreq-exynos one when "performance" cpufreq governor was used on Exynos4210 SoC based Origen board), this was probably meant to be workarounded by use of CLK_GET_RATE_NOCACHE and CLK_DIVIDER_READ_ONLY clock flags in the original patchset (in "[PATCH v12 6/6] clk: samsung: remove unused clock aliases and update clock flags") but using these flags is not sufficient to fix the issue observed - removed Exynos5250 and Exynos5420 support for now 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>
