Adds generic PM domain support for Tegra SoCs but this series only enables support for it on Tegra 64-bit devices. There is no reason why this cannot be enable for Tegra 32-bit devices, but to keep the patch series to a minimum only 64-bit devices are enabled so far. This series has been boot tested on Tegra210 as well as various 32-bit Tegra platforms. Summary of changes since V4 [1]: - Re-worked fix to handle base address on probe failure - Added patch to lock around simultaneuous accesses to PMC registers - Added patch to change powergate and rail IDs to unsigned type - Added patch to fix testing of powergate state - Updated patch to check for valid powergates to use a bitmap - Updated Tegra DT PMC bindings per Rob H's feedback - Updated Tegra power domains binding per Thierry's feedback - Updated Tegra generic power domain support per Thierry's feedback Summary of changes since V3 [0]: - Dropped tegra124 support for now - Removed MC flush support per feedback from Thierry - Cleaned up the PMC changes per feedback from Thierry - Added support for tegra210 Series Summary: Patch 1-7: PMC clean-up and fixes Patch 8: Adds function to remove a generic PM domain Patch 9: Updates DT documentation for tegra PMC Patch 10: Adds DT documentation for tegra generic PM domains Patch 11: Adds PMC generic DM domains support Patch 12: Adds audio clock for Tegra210 audio power-domain Patch 13: Adds DT bindings for Tegra210 audio power-domain Patch 14: Enable generic PM domains for tegra64 [0] http://comments.gmane.org/gmane.linux.ports.tegra/22944 [1] http://marc.info/?l=linux-tegra&m=144924153600529&w=2 Jon Hunter (14): soc: tegra: pmc: Restore base address on probe failure soc: tegra: pmc: Protect public functions from potential race conditions soc: tegra: pmc: Change powergate and rail IDs to be an unsigned type soc: tegra: pmc: Fix testing of powergate state soc: tegra: pmc: Wait for powergate state to change soc: tegra: pmc: Fix checking of valid partitions soc: tegra: pmc: Ensure partitions can be toggled on/off by PMC PM / Domains: Add function to remove a pm-domain Documentation: DT: bindings: Update NVIDIA PMC for Tegra Documentation: DT: bindings: Add power domain info for NVIDIA PMC soc: tegra: pmc: Add generic PM domain support clk: tegra210: Add the APB2APE audio clock ARM64: tegra: Add audio PM domain device node for Tegra210 ARM64: tegra: select PM_GENERIC_DOMAINS .../bindings/arm/tegra/nvidia,tegra20-pmc.txt | 67 ++- arch/arm/mach-tegra/platsmp.c | 16 +- arch/arm64/Kconfig.platforms | 2 + arch/arm64/boot/dts/nvidia/tegra210.dtsi | 11 +- drivers/base/power/domain.c | 26 + drivers/clk/tegra/clk-id.h | 1 + drivers/clk/tegra/clk-tegra-periph.c | 1 + drivers/clk/tegra/clk-tegra210.c | 1 + drivers/gpu/drm/tegra/drm.h | 2 +- drivers/soc/tegra/pmc.c | 603 ++++++++++++++++++--- include/dt-bindings/clock/tegra210-car.h | 2 +- include/dt-bindings/power/tegra-powergate.h | 36 ++ include/linux/pm_domain.h | 5 + include/soc/tegra/pmc.h | 73 +-- 14 files changed, 709 insertions(+), 137 deletions(-) create mode 100644 include/dt-bindings/power/tegra-powergate.h -- 2.1.4 -- 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
