In exynos-bus instead of using regulator_set_voltage_tol() with default voltage tolerance it should be used regulator_set_voltage_triplet() with volatege range, and this is already present in opp/core.c code, so it can be reused. While at this, move setting regulators into opp/core. This patchset was tested on Odroid XU3. The DTS coupled regulators patch depends on 2nd and 3rd patches. Changes: v3: - added new exynos-bus patch to correct clock and regulator enabling and disabling sequence as suggested by Chanwoo Choi - corrected error path in enable and improved commit message in opp/core - improve comment in devfreq/exynos-bus.c before devfreq_recommended_opp() - change cover letter as there is new patch - added note before Signed-off-by in 4th patch v2: - improve regulators enable/disable code in opp/core as suggested by Viresh Kumar - add new patch for remove unused dt-bindings as suggested by Krzysztof Kozlowski Regards, Kamil Kamil Konieczny (4): devfreq: exynos-bus: correct clock enable sequence opp: core: add regulators enable and disable devfreq: exynos-bus: convert to use dev_pm_opp_set_rate() dt-bindings: devfreq: exynos-bus: remove unused property Marek Szyprowski (1): ARM: dts: exynos: add initial data for coupled regulators for Exynos5422/5800 .../bindings/devfreq/exynos-bus.txt | 2 - arch/arm/boot/dts/exynos5420.dtsi | 34 ++-- arch/arm/boot/dts/exynos5422-odroid-core.dtsi | 4 + arch/arm/boot/dts/exynos5800-peach-pi.dts | 4 + arch/arm/boot/dts/exynos5800.dtsi | 32 ++-- drivers/devfreq/exynos-bus.c | 181 ++++++------------ drivers/opp/core.c | 16 +- 7 files changed, 113 insertions(+), 160 deletions(-)
