All patches should go via Tegra tree because they are interdependent, please review and ack. If you haven't seen this series before, that's because I wanted to finalize the GENPD part at first and didn't bother you previously. Changelog: v8: - Added new generic dev_pm_opp_sync() helper that syncs OPP state with hardware. All drivers changed to use it. This replaces GENPD attach_dev callback hacks that were used in v7. - Added new patch patch "soc/tegra: regulators: Prepare for suspend" that fixes dying Tegra20 SoC after enabling VENC power domain during resume from suspend. It matches to what downstream kernel does on suspend/resume. - After a second thought, I dropped patches which added RPM to memory drivers since hardware is always-on and RPM not needed. - Replaced the "dummy host1x driver" patch with new "Disable unused host1x hardware" patch, since it's a cleaner solution. Dmitry Osipenko (34): opp: Add dev_pm_opp_sync() helper soc/tegra: pmc: Disable PMC state syncing soc/tegra: Don't print error message when OPPs not available soc/tegra: Add devm_tegra_core_dev_init_opp_table_simple() soc/tegra: Use dev_pm_opp_sync() dt-bindings: clock: tegra-car: Document new tegra-clocks sub-node clk: tegra: Support runtime PM and power domain dt-bindings: host1x: Document OPP and power domain properties dt-bindings: host1x: Document Memory Client resets of Host1x, GR2D and GR3D gpu: host1x: Add host1x_channel_stop() gpu: host1x: Add runtime PM and OPP support drm/tegra: dc: Support OPP and SoC core voltage scaling drm/tegra: hdmi: Add OPP support drm/tegra: gr2d: Support power management drm/tegra: gr3d: Support power management drm/tegra: vic: Support system suspend usb: chipidea: tegra: Add runtime PM and OPP support bus: tegra-gmi: Add runtime PM and OPP support pwm: tegra: Add runtime PM and OPP support mmc: sdhci-tegra: Add runtime PM and OPP support mtd: rawnand: tegra: Add runtime PM and OPP support spi: tegra20-slink: Add OPP support media: dt: bindings: tegra-vde: Convert to schema media: dt: bindings: tegra-vde: Document OPP and power domain media: staging: tegra-vde: Support generic power domain and OPP soc/tegra: fuse: Add OPP support soc/tegra: fuse: Reset hardware soc/tegra: regulators: Prepare for suspend soc/tegra: pmc: Enable core domain support for Tegra20 and Tegra30 ARM: tegra: Add OPP tables and power domains to Tegra20 device-trees ARM: tegra: Add OPP tables and power domains to Tegra30 device-trees ARM: tegra: Add Memory Client resets to Tegra20 GR2D, GR3D and Host1x ARM: tegra: Add Memory Client resets to Tegra30 GR2D, GR3D and Host1x ARM: tegra20/30: Disable unused host1x hardware .../bindings/clock/nvidia,tegra20-car.yaml | 51 + .../display/tegra/nvidia,tegra20-host1x.txt | 53 + .../bindings/media/nvidia,tegra-vde.txt | 64 - .../bindings/media/nvidia,tegra-vde.yaml | 119 ++ .../boot/dts/tegra20-acer-a500-picasso.dts | 1 + arch/arm/boot/dts/tegra20-colibri.dtsi | 3 +- arch/arm/boot/dts/tegra20-harmony.dts | 3 +- arch/arm/boot/dts/tegra20-paz00.dts | 1 + .../arm/boot/dts/tegra20-peripherals-opp.dtsi | 941 +++++++++++ arch/arm/boot/dts/tegra20-seaboard.dts | 3 +- arch/arm/boot/dts/tegra20-tamonten.dtsi | 3 +- arch/arm/boot/dts/tegra20-trimslice.dts | 9 + arch/arm/boot/dts/tegra20-ventana.dts | 1 + arch/arm/boot/dts/tegra20.dtsi | 119 +- .../tegra30-asus-nexus7-grouper-common.dtsi | 1 + arch/arm/boot/dts/tegra30-beaver.dts | 1 + arch/arm/boot/dts/tegra30-cardhu.dtsi | 1 + arch/arm/boot/dts/tegra30-colibri.dtsi | 17 +- arch/arm/boot/dts/tegra30-ouya.dts | 1 + .../arm/boot/dts/tegra30-peripherals-opp.dtsi | 1412 +++++++++++++++++ arch/arm/boot/dts/tegra30.dtsi | 181 ++- drivers/bus/tegra-gmi.c | 92 +- drivers/clk/tegra/Makefile | 1 + drivers/clk/tegra/clk-device.c | 222 +++ drivers/clk/tegra/clk-pll.c | 2 +- drivers/clk/tegra/clk-super.c | 2 +- drivers/clk/tegra/clk-tegra20.c | 39 +- drivers/clk/tegra/clk-tegra30.c | 70 +- drivers/clk/tegra/clk.c | 64 + drivers/clk/tegra/clk.h | 2 + drivers/gpu/drm/tegra/dc.c | 74 + drivers/gpu/drm/tegra/dc.h | 2 + drivers/gpu/drm/tegra/gr2d.c | 154 +- drivers/gpu/drm/tegra/gr3d.c | 393 ++++- drivers/gpu/drm/tegra/hdmi.c | 15 +- drivers/gpu/drm/tegra/vic.c | 4 + drivers/gpu/host1x/channel.c | 8 + drivers/gpu/host1x/debug.c | 15 + drivers/gpu/host1x/dev.c | 157 +- drivers/gpu/host1x/dev.h | 3 +- drivers/gpu/host1x/hw/channel_hw.c | 44 +- drivers/gpu/host1x/intr.c | 3 - drivers/gpu/host1x/syncpt.c | 5 +- drivers/mmc/host/sdhci-tegra.c | 146 +- drivers/mtd/nand/raw/tegra_nand.c | 62 +- drivers/opp/core.c | 42 +- drivers/pwm/pwm-tegra.c | 104 +- drivers/soc/tegra/common.c | 34 +- drivers/soc/tegra/fuse/fuse-tegra.c | 36 + drivers/soc/tegra/fuse/fuse.h | 1 + drivers/soc/tegra/pmc.c | 17 + drivers/soc/tegra/regulators-tegra20.c | 99 ++ drivers/soc/tegra/regulators-tegra30.c | 122 ++ drivers/spi/spi-tegra20-slink.c | 15 +- drivers/staging/media/tegra-vde/vde.c | 65 +- drivers/usb/chipidea/ci_hdrc_tegra.c | 61 +- include/linux/host1x.h | 1 + include/linux/pm_opp.h | 6 + include/soc/tegra/common.h | 13 + 59 files changed, 4796 insertions(+), 384 deletions(-) delete mode 100644 Documentation/devicetree/bindings/media/nvidia,tegra-vde.txt create mode 100644 Documentation/devicetree/bindings/media/nvidia,tegra-vde.yaml create mode 100644 drivers/clk/tegra/clk-device.c
