Hi, in this version I fixed the issues Shawn pointed out last time. Old blurb, fast-forward if you followed previous iterations: The i.MX6Q can gate off the CPU and PU (GPU/VPU) power domains using the Power Gating Controller (PGC) in the GPC register space. The CPU power domain is already handled by wait state code, but the PU power domain can be controlled using the generic power domain framework and power off the PU supply regulator if all devices in the power domain are (runtime) suspended. This patchset adds a GPC platform device initialized at subsys_initcall time (after anatop regulators) that binds to the gpc device tree node and sets up the PU power domain. The GPC node becomes a power-controller as defined by Tomasz' OF power domain bindings. This series depends on the patches "drivercore: Bind/unbind power domain on probe/remove" and "base: power: Add generic OF-based power domain look-up". Changes since v5: - Fixed compilation for !CONFIG_PM case - Added #define for clock array size - Keep "fsl,imx6q-gpc" compatible value for i.MX6SL gpc node Philipp Zabel (5): Documentation: Add device tree bindings for Freescale i.MX GPC ARM: imx6: gpc: Add PU power domain for GPU/VPU ARM: dts: imx6qdl: Add power-domain information to gpc node ARM: dts: imx6sl: Add power-domain information to gpc node ARM: dts: imx6qdl: Allow disabling the PU regulator, add a enable ramp delay .../devicetree/bindings/power/fsl,imx-gpc.txt | 54 ++++++ arch/arm/boot/dts/imx6qdl.dtsi | 7 +- arch/arm/boot/dts/imx6sl.dtsi | 4 + arch/arm/mach-imx/Kconfig | 1 + arch/arm/mach-imx/gpc.c | 203 +++++++++++++++++++++ 5 files changed, 268 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/power/fsl,imx-gpc.txt -- 1.9.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
