syscore: Pass context data to callbacks

2025-11-14T09:01:52+00:00

Several drivers can benefit from registering per-instance data along with the syscore operations. To achieve this, move the modifiable fields out of the syscore_ops structure and into a separate struct syscore that can be registered with the framework. Add a void * driver data field for drivers to store contextual data that will be passed to the syscore ops. Acked-by: Rafael J. Wysocki (Intel) Signed-off-by: Thierry Reding

powerpc: Switch to irq_find_mapping()

2025-05-16T19:06:12+00:00

irq_linear_revmap() is deprecated, so remove all its uses and supersede them by an identical call to irq_find_mapping().

powerpc: Switch to irq_domain_create_*()

2025-05-16T19:06:11+00:00

irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

irqdomain: Rename irq_set_default_host() to irq_set_default_domain()

2025-04-04T14:39:10+00:00

Naming interrupt domains host is confusing at best and the irqdomain code uses both domain and host inconsistently. Therefore rename irq_set_default_host() to irq_set_default_domain().

powerpc/ipic: Stop printing address of registers

2025-02-24T06:56:21+00:00

The following line appears at boot: IPIC (128 IRQ sources) at (ptrval) This is pointless so remove the printing of the virtual address and replace it by matching physical address.

powerpc: Add missing headers

2022-05-08T12:15:40+00:00

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h, asm/pci.h etc... Include the needed headers, and remove asm/prom.h when it was needed exclusively for pulling necessary headers.

powerpc/sysdev: Add __init attribute to eligible functions

2021-12-23T11:33:12+00:00

Some files functions in 'arch/powerpc/sysdev' are deserving of an `__init` macro attribute. These functions are only called by other initialization functions and therefore should inherit the attribute. Also, change function declarations in header files to include `__init`.
