This moves remaining AMBA ACPI devices into respective platform drivers for enabling ACPI based power management support. This series applies on kernel v6.8-rc1 release. 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_v4) 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 V4: - Fixed PM imbalance in etm4_probe() error path with pm_runtime_disable() - Restored back the pm_runtime_disable() on platform probe error paths in replicator, funnel, catu, tpiu, tmc and stm devices - Dropped dev_caps argument from __tmc_probe() - Changed xxxx_platform_remove() for platform_driver->remove_new() callback Changes in V3: https://lore.kernel.org/all/20231208053939.42901-1-anshuman.khandual@xxxxxxx/ - Split coresight_init_driver/remove_driver() helpers into a separate patch - Added 'drvdata->pclk' comments in replicator, funnel, tpiu, tmc, and stm devices - Updated funnel, and replicator drivers to use these new helpers - Check for drvdata instead of drvdata->pclk in suspend and resume paths in catu, tmc and debug devices - Added patch to extract device name from AMBA pid based table lookup for stm - Added patch to extract device properties from AMBA pid based table look for tmc - Dropped pm_runtime_put() from common __probe() functions - Handled pm_runtime_put() in AMBA driver in success path - Handled pm_runtime_put() in platform driver in both success and error paths Changes in V2: https://lore.kernel.org/all/20231201062053.1268492-1-anshuman.khandual@xxxxxxx/ - 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 (11): coresight: etm4x: Fix unbalanced pm_runtime_enable() coresight: stm: Extract device name from AMBA pid based table lookup coresight: tmc: Extract device properties from AMBA pid based table lookup coresight: Add helpers registering/removing both AMBA and platform drivers 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 | 142 +++++++++++++--- drivers/hwtracing/coresight/coresight-catu.h | 1 + drivers/hwtracing/coresight/coresight-core.c | 29 ++++ .../hwtracing/coresight/coresight-cpu-debug.c | 141 ++++++++++++++-- .../coresight/coresight-etm4x-core.c | 3 + .../hwtracing/coresight/coresight-funnel.c | 86 +++++----- drivers/hwtracing/coresight/coresight-priv.h | 10 ++ .../coresight/coresight-replicator.c | 81 ++++----- drivers/hwtracing/coresight/coresight-stm.c | 117 +++++++++++-- .../hwtracing/coresight/coresight-tmc-core.c | 158 +++++++++++++++--- drivers/hwtracing/coresight/coresight-tmc.h | 2 + drivers/hwtracing/coresight/coresight-tpiu.c | 102 +++++++++-- include/linux/coresight.h | 7 + 14 files changed, 726 insertions(+), 161 deletions(-) -- 2.25.1
