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: 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: use subsys_initcall for Freescale Local Bus

2015-06-16T18:12:34+00:00

The FSL_SOC option is bool, and hence this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of subsys_initcall (which makes sense for bus code) will thus change this registration from level 6-device to level 4-subsys (i.e. slightly earlier). However no observable impact of that small difference has been observed during testing, or is expected.

powerpc/85xx: handle the eLBC error interrupt if it exists in dts

2014-01-10T23:19:27+00:00

On P1020, P1021, P1022, and P1023, eLBC event interrupts are routed to internal interrupt 3 while ELBC error interrupts are routed to internal interrupt 0. We need to call request_irq for each.
