This moves remaining AMBA ACPI devices into respective platform drivers for enabling ACPI based power management support. 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 <lpieralisi@xxxxxxxxxx> Cc: Sudeep Holla <sudeep.holla@xxxxxxx> Cc: Suzuki K Poulose <suzuki.poulose@xxxxxxx> Cc: Mike Leach <mike.leach@xxxxxxxxxx> Cc: James Clark <james.clark@xxxxxxx> Cc: Maxime Coquelin <mcoquelin.stm32@xxxxxxxxx> Cc: Alexandre Torgue <alexandre.torgue@xxxxxxxxxxx> Cc: linux-acpi@xxxxxxxxxxxxxxx Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx Cc: linux-kernel@xxxxxxxxxxxxxxx Cc: coresight@xxxxxxxxxxxxxxxx Cc: linux-stm32@xxxxxxxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxx/ - 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@xxxxxxx/ 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(-) -- 2.25.1
