Hi Thomas, the series is ok for me. Is it possible to pull these changes directly in tip/timers/core? There is a single trivial conflict with a trace. -- Daniel > > The following changes since commit d003d029cea8a28139b4f9b88a36b8fac864f45b: > > arm64: arch_timer: Add HISILICON_ERRATUM_161010101 ACPI matching data (2017-04-07 11:22:10 +0100) > > are available in the git repository at: > > git://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git tags/arch-timer-gtdt > > for you to fetch changes up to ca9ae5ec4ef0ed13833b03297ab319676965492c: > > acpi/arm64: Add SBSA Generic Watchdog support in GTDT driver (2017-04-19 17:00:15 +0100) > > ---------------------------------------------------------------- > arch timer GTDT patches > > - arch_timer cleanups and refactoring > - new common GTDT parser > - GTDT-based MMIO arch_timer support > - GTDT-based SBSA watchdog support > > ---------------------------------------------------------------- > Fu Wei (16): > clocksource: arm_arch_timer: clean up printk usage > clocksource: arm_arch_timer: rename type macros > clocksource: arm_arch_timer: rename the PPI enum > clocksource: arm_arch_timer: move enums and defines to header file > clocksource: arm_arch_timer: add a new enum for spi type > clocksource: arm_arch_timer: rework PPI selection > clocksource: arm_arch_timer: split dt-only rate handling > clocksource: arm_arch_timer: refactor arch_timer_needs_probing > clocksource: arm_arch_timer: move arch_timer_needs_of_probing into DT init call > clocksource: arm_arch_timer: add structs to describe MMIO timer > clocksource: arm_arch_timer: split MMIO timer probing. > acpi/arm64: Add GTDT table parse driver > clocksource: arm_arch_timer: simplify ACPI support code. > acpi/arm64: Add memory-mapped timer support in GTDT driver > clocksource: arm_arch_timer: add GTDT support for memory-mapped timer > acpi/arm64: Add SBSA Generic Watchdog support in GTDT driver > > arch/arm64/Kconfig | 1 + > drivers/acpi/arm64/Kconfig | 3 + > drivers/acpi/arm64/Makefile | 1 + > drivers/acpi/arm64/gtdt.c | 417 +++++++++++++++++++++++++ > drivers/clocksource/arm_arch_timer.c | 573 +++++++++++++++++++++++------------ > include/clocksource/arm_arch_timer.h | 34 +++ > include/linux/acpi.h | 7 + > 7 files changed, 834 insertions(+), 202 deletions(-) > create mode 100644 drivers/acpi/arm64/gtdt.c

Hi Daniel, The series enables support for the MMIO architected timers (useful for system-level idle), which need to be probed via the GTDT when using ACPI. I realise this is a little late, but I would very much appreciate if you could pull these arch timer GTDT patches for v4.12. The series has been largely fine for a while now, and the major hold-ups were edge cases in error handling which have now been addressed. The bulk of the series is a refactoring to cleanly separate the core driver, DT probe path, and ACPI probe path. The final patch of the series adds GTDT-based probing of the SBSA watchdog, using the new GTDT probing infrastructure. I've tested the patches on arm and arm64 platforms. The ACPI parts have all been appropriately acked, and it's preferred that these all go through the clocksource tree. The series is based on Marc's arch-timer-errata tag, which is alread in tip/timers/core. Thanks, Mark.
