This series applies on latest coresight/next branch. This series has been built, and boot tested on a DT based coresight platform. Although this still requires some more testing on ACPI based coresight platforms. https://git.gitlab.arm.com/linux-arm/linux-anshuman.git (amba_other_acpi_migration_v2) Cc: Lorenzo Pieralisi Cc: Sudeep Holla Cc: Suzuki K Poulose Cc: Mike Leach Cc: James Clark Cc: Maxime Coquelin Cc: Alexandre Torgue Cc: linux-acpi@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org Cc: linux-kernel@vger.kernel.org Cc: coresight@lists.linaro.org Cc: linux-stm32@st-md-mailman.stormreply.com Changes in V2: - Dropped redundant devm_ioremap_resource() hunk from tmc_platform_probe() - Defined coresight_[init|remove]_driver() for both AMBA/platform drivers - Changed catu, tmc, tpiu, stm and debug coresight drivers to use the new helpers avoiding build issues arising from module_amba_driver(), and module_platform_driver() being on the same file Changes in V1: https://lore.kernel.org/all/20231027072943.3418997-1-anshuman.khandual@arm.com/ - Replaced all IS_ERR() instances with IS_ERR_OR_NULL() as per Suzuki Changes in RFC: https://lore.kernel.org/all/20230921042040.1334641-1-anshuman.khandual@arm.com/ Anshuman Khandual (7): coresight: replicator: Move ACPI support from AMBA driver to platform driver coresight: funnel: Move ACPI support from AMBA driver to platform driver coresight: catu: Move ACPI support from AMBA driver to platform driver coresight: tpiu: Move ACPI support from AMBA driver to platform driver coresight: tmc: Move ACPI support from AMBA driver to platform driver coresight: stm: Move ACPI support from AMBA driver to platform driver coresight: debug: Move ACPI support from AMBA driver to platform driver drivers/acpi/arm64/amba.c | 8 - drivers/hwtracing/coresight/coresight-catu.c | 130 +++++++++++++--- drivers/hwtracing/coresight/coresight-catu.h | 1 + drivers/hwtracing/coresight/coresight-core.c | 29 ++++ .../hwtracing/coresight/coresight-cpu-debug.c | 141 ++++++++++++++++-- .../hwtracing/coresight/coresight-funnel.c | 49 +++--- .../coresight/coresight-replicator.c | 44 +++--- drivers/hwtracing/coresight/coresight-stm.c | 91 +++++++++-- .../hwtracing/coresight/coresight-tmc-core.c | 130 ++++++++++++++-- drivers/hwtracing/coresight/coresight-tmc.h | 1 + drivers/hwtracing/coresight/coresight-tpiu.c | 87 ++++++++++- include/linux/coresight.h | 7 + 12 files changed, 608 insertions(+), 110 deletions(-)
