We also make use of some new generic macros for polling hardware registers. Changes since v1: - Renamed one of the iopoll macros to use the more standard `_atomic' suffix - Removed some convenience iopoll wrappers to encourage explicitness Matt Wagantall (1): iopoll: Introduce memory-mapped IO polling macros Mitchel Humpherys (1): iommu/arm-smmu: add support for iova_to_phys through ATS1PR drivers/iommu/arm-smmu.c | 73 ++++++++++++++++++++++++++++++++++++++++++++- include/linux/iopoll.h | 77 ++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 149 insertions(+), 1 deletion(-) create mode 100644 include/linux/iopoll.h -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, hosted by The Linux Foundation
