2014-09-03clk: prevent erronous parsing of children during rate changeTero Kristo
In some cases, clocks can switch their parent with clk_set_rate, for example clk_mux can do this in some cases. Current implementation of clk_change_rate uses un-safe list iteration on the clock children, which will cause wrong clocks to be parsed in case any of the clock children change their parents during the change rate operation. Fixed by using the safe list iterator instead. The problem was detected due to some divide by zero errors generated by clock init on dra7-evm board, see discussion under http://article.gmane.org/gmane.linux.ports.arm.kernel/349180 for details.

2014-09-02clk: qcom: Fix sdc 144kHz frequency entryStephen Boyd
The pre-divider for the sdc clocks only has 2 bits in it, so we can't possibly divide by anything larger than 4 here. Furthermore, we program the value of ~(n - m) and the n value is larger than 8 bits (max of 256). Replace this entry with 200kHz which is close enough to 144kHz to be usable.

This patch is the Flexgen implementation reusing as much as possible of Common Clock Framework functions. The idea is to have an instance of "struct flexgen" per output clock. It represents the clock cross bar (by a mux element), and the pre and final dividers (using dividers and gates elements).

2014-07-26clk: samsung: exynos4: Enable ARMCLK down featureKrzysztof Kozlowski
Enable ARMCLK down feature on all Exynos4 SoCs. The frequency of ARMCLK will be reduced upon entering idle mode (WFI or WFE). The feature behaves like very fast cpufreq ondemand governor. In idle mode this reduces energy consumption on full frequency chosen by cpufreq governor by approximately: - Trats2: 6.5% (153 mA -> 143 mA) - Trats: 33.0% (180 mA -> 120 mA) - Gear1: 27.0% (180 mA -> 130 mA) The patch uses simillar settings as Exynos5250 (clk-exynos5250.c), except it disables clock up feature and on Exynos4412 ARMCLK down is enabled for all 4 cores. Tested on Trats board (Exynos4210), Trats2 board (Exynos4412) and Samsung Gear 1 (Exynos4212).
