Wysocki" Cc: Linux PM mailing list , Linux Kernel Mailing List , Lorenzo Pieralisi , Kevin Hilman [resent because of the missing Cc] Hi Rafael, this pull request contains the following changes: * Lorenzo Pieralisi implemented a framework to initialize the ARM=20 cpuidle drivers with the DT. As an example, it provided a couple of=20 drivers using it: arm64 and big little. The former one is a new driver=20 while the latter is a change. There was also a patch for Exynos allowin= g=20 to use this framework but as it depends on a change in Samsung's tree, = I=20 postponed this patch until the change is visible after the merge. The=20 set of changes depends on some other changes made in the ARM64 tree, fo= r=20 this reason a shared branch is used. This is why there is a merge from=20 arm64 in my pull request. I believe we already used this procedure. * Kevin Hilman added the compatible string for the exynos 5800 in the= DT Thanks ! -- Daniel The following changes since commit 0f33be009b89d2268e94194dc4fd01a7851b= 6d51: Linux 3.17-rc6 (2014-09-21 15:43:02 -0700) are available in the git repository at: https://git.linaro.org/people/daniel.lezcano/linux.git cpuidle/3.18 for you to fetch changes up to d2e5c871ed8a250f7ee1fe34dd52ed5757363fba= : drivers: cpuidle: initialize big.LITTLE driver through DT (2014-09-2= 5=20 10:52:21 +0200) ---------------------------------------------------------------- Daniel Lezcano (1): Merge branch 'for-next/cpuidle' of=20 git://git.kernel.org/.../arm64/linux into cpuidle/3.18 Kevin Hilman (1): cpuidle: big.LITTLE: add Exynos5800 compatible string Lorenzo Pieralisi (7): Documentation: arm: define DT idle states bindings arm64: kernel: refactor the CPU suspend API for retention states arm64: kernel: introduce cpu_init_idle CPU operation arm64: add PSCI CPU_SUSPEND based cpu_suspend support drivers: cpuidle: implement DT based idle states infrastructure drivers: cpuidle: CPU idle ARM64 driver drivers: cpuidle: initialize big.LITTLE driver through DT Documentation/devicetree/bindings/arm/cpus.txt | 8 + .../devicetree/bindings/arm/idle-states.txt | 679=20 +++++++++++++++++++++ Documentation/devicetree/bindings/arm/psci.txt | 14 +- arch/arm/boot/dts/vexpress-v2p-ca15_a7.dts | 23 + arch/arm64/include/asm/cpu_ops.h | 3 + arch/arm64/include/asm/cpuidle.h | 13 + arch/arm64/include/asm/suspend.h | 1 + arch/arm64/kernel/Makefile | 1 + arch/arm64/kernel/cpuidle.c | 31 + arch/arm64/kernel/psci.c | 104 ++++ arch/arm64/kernel/sleep.S | 47 +- arch/arm64/kernel/suspend.c | 48 +- drivers/cpuidle/Kconfig | 8 + drivers/cpuidle/Kconfig.arm | 1 + drivers/cpuidle/Kconfig.arm64 | 14 + drivers/cpuidle/Makefile | 5 + drivers/cpuidle/cpuidle-arm64.c | 133 ++++ drivers/cpuidle/cpuidle-big_little.c | 20 + drivers/cpuidle/dt_idle_states.c | 213 +++++++ drivers/cpuidle/dt_idle_states.h | 7 + 20 files changed, 1340 insertions(+), 33 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/idle-states.= txt create mode 100644 arch/arm64/include/asm/cpuidle.h create mode 100644 arch/arm64/kernel/cpuidle.c create mode 100644 drivers/cpuidle/Kconfig.arm64 create mode 100644 drivers/cpuidle/cpuidle-arm64.c create mode 100644 drivers/cpuidle/dt_idle_states.c create mode 100644 drivers/cpuidle/dt_idle_states.h --=20 Linaro.org =E2=94=82 Open source software fo= r ARM SoCs =46ollow Linaro: Facebook | Twitter | Blog
