2026-07-07T00:42:01+00:00

Tejun changd percpu_ref to use long instead of int back in 2014 but missed updating this bit of the documentation. Also add the documentation to the htmldocs.

dpll: add STATE_CONNECTED_OVERRIDE pin capability

2026-07-06T12:45:04+00:00

Add DPLL_PIN_CAPABILITIES_STATE_CONNECTED_OVERRIDE capability flag that indicates a pin can be set to connected regardless of the current DPLL device mode, overriding the active input selection. This is useful for automatic-only DPLL devices where mode cannot be switched to manual, allowing userspace to directly connect such pin from automatic mode. The capability requires STATE_CAN_CHANGE to be set as well; dpll_pin_register() warns if a driver violates this. Document the new capability in the Pin selection section of Documentation/driver-api/dpll.rst.

ACPI: bus: Eliminate struct acpi_driver

2026-07-06T11:31:50+00:00

Now that struct acpi_driver has no more users, eliminate it along with all of the code related to it. Also remove the file added by commit b8c8a8ea18ad ("ACPI: Documentation: driver-api: Disapprove of using ACPI drivers") because it will not be necessary any more after eliminating struct acpi_driver from the code. No intentional functional impact. Signed-off-by: Rafael J. Wysocki Reviewed-by: Andy Shevchenko Reviewed-by: Danilo Krummrich Link: https://patch.msgid.link/5132944.31r3eYUQgx@rafael.j.wysocki

dmaengine: Add API to combine configuration and preparation (sg and single)

2026-06-30T11:12:30+00:00

Previously, configuration and preparation required two separate calls. This works well when configuration is done only once during initialization. However, in cases where the burst length or source/destination address must be adjusted for each transfer, calling two functions is verbose and requires additional locking to ensure both steps complete atomically. Add a new API dmaengine_prep_config_single() and dmaengine_prep_config_sg() and callback device_prep_config_sg() that combines configuration and preparation into a single operation. If the configuration argument is passed as NULL, fall back to the existing implementation.
