From: "jinkun.hong" <jinkun.hong@xxxxxxxxxxxxxx> Add power domain drivers based on generic power domain for Rockchip platform, and support RK3288. https://chromium-review.googlesource.com/#/c/220253/9 This is the GPU driver, add the following information in DT, and it can support the PMDOMAIN. gpu: gpu@ffa30000 { compatible = "arm,malit764", "arm,malit76x", "arm,malit7xx", "arm,mali-midgard"; reg = <0xffa30000 0x10000>; interrupts = <GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>, <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>, <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>; interrupt-names = "JOB", "MMU", "GPU"; clocks = <&cru ACLK_GPU>; clock-names = "aclk_gpu"; operating-points = < /* KHz uV */ 100000 800000 200000 850000 300000 950000 400000 1000000 600000 1150000 >; power-domains = <&gpu_power>; status = "disabled"; }; Based on: - [PATCH v1 1/4] PM / clock_ops: Add pm_clk_add_clk() http://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg735599.html Changes in v6: - delete pmu_lock - modify dev_lock using mutex - pm_clk_resume(pd->dev) change to pm_clk_resume(ed->dev) - pm_clk_suspend(pd->dev) change to pm_clk_suspend(ed->dev) - add devm_kfree(pd->dev, de) in rockchip_pm_domain_detach_dev Changes in v5: - delete idle_lock - add timeout in rockchip_pmu_set_idle_request() Changes in v4: - use list storage dev Changes in v3: - change use pm_clk_resume() and pm_clk_suspend() - DT structure has changed - Decomposition power-controller, changed to multiple controller (gpu-power-controller, hevc-power-controller) Changes in v2: - remove the "pd->pd.of_node = np" - move clocks to "optional" - make pd_vio clocks all one entry per line and alphabetize. - power: power-controller move back to pinctrl: pinctrl. jinkun.hong (3): power-domain: add power domain drivers for Rockchip platform dt-bindings: add document of Rockchip power domain ARM: dts: add rk3288 power-domain node .../bindings/arm/rockchip/power_domain.txt | 46 +++ arch/arm/boot/dts/rk3288.dtsi | 24 ++ arch/arm/mach-rockchip/Kconfig | 1 + arch/arm/mach-rockchip/Makefile | 1 + arch/arm/mach-rockchip/pm_domains.c | 358 ++++++++++++++++++++ 5 files changed, 430 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/rockchip/power_domain.txt create mode 100644 arch/arm/mach-rockchip/pm_domains.c -- 1.7.9.5 -- 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
