powerpc/cpm2: Remove cpm2_map() and cpm2_unmap()

2023-08-16T13:54:47+00:00

Since commit 449012daa92a ("[POWERPC] cpm2: Infrastructure code cleanup.") cpm2_map() is just returning cpm2_immr pointer and cpm2_unmap() does nothing. We already have parts of code that use cpm2_immr directly so get rid of cpm2_map() and cpm2_unmap() by using cpm2_immr directly. And avoid going through local pointers that hide the pointed structure.

powerpc/include: Remove mpc8260.h and m82xx_pci.h

2023-08-16T13:54:47+00:00

SIU_INT_IRQ1 is not used anywhere and __IO_BASE is defined in asm/io.h Remove m82xx_pci.h Then the only thing remaining in mpc8260.h is MPC82XX_BCR_PLDP Move MPC82XX_BCR_PLDP into asm/cpm2.h then remove mpc8260.h Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://msgid.link/afe23bf3624c389ff17e9789884c78c124b7b202.1691474658.git.christophe.leroy@csgroup.eu

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/cpm2: Use irq_set_handler_locked()

2015-09-16T13:43:10+00:00

Use irq_set_handler_locked() as it avoids a redundant lookup of the irq descriptor.

powerpc: Delete non-required instances of include

2014-01-15T02:46:44+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. The one instance where we add an include for init.h covers off a case where that file was implicitly getting it from another header which itself didn't need it.

powerpc/irqdomain: Fix broken NR_IRQ references

2012-04-30T00:45:26+00:00

The switch from using irq_map to irq_alloc_desc*() for managing irq number allocations introduced new bugs in some of the powerpc interrupt code. Several functions rely on the value of NR_IRQS to determine the maximum irq number that could get allocated. However, with sparse_irq and using irq_alloc_desc*() the maximum possible irq number is now specified with 'nr_irqs' which may be a number larger than NR_IRQS. This has caused breakage on powermac when CONFIG_NR_IRQS is set to 32. This patch removes most of the direct references to NR_IRQS in the powerpc code and replaces them with either a nr_irqs reference or by using the common for_each_irq_desc() macro. The powerpc-specific for_each_irq() macro is removed at the same time. Also, the Cell axon_msi driver is refactored to remove the global build assumption on the size of NR_IRQS and instead add a limit to the maximum irq number when calling irq_domain_add_nomap().

irq_domain/powerpc: Replace custom xlate functions with library functions

2012-02-16T13:11:24+00:00

This patch converts a number of the powerpc drivers to use the common library of irq_domain xlate functions, dropping a bunch of lines in the process. v5: - Remove tsi108 changes from patch Signed-off-by: Grant Likely Cc: Rob Herring Cc: Benjamin Herrenschmidt Cc: Thomas Gleixner Cc: Milton Miller Tested-by: Olof Johansson

irq_domain: Replace irq_alloc_host() with revmap-specific initializers

2012-02-16T13:11:22+00:00

Each revmap type has different arguments for setting up the revmap. This patch splits up the generator functions so that each revmap type can do its own setup and the user doesn't need to keep track of how each revmap type handles the arguments. This patch also adds a host_data argument to the generators. There are cases where the host_data pointer will be needed before the function returns. ie. the legacy map calls the .map callback for each irq before returning. v2: - Add void *host_data argument to irq_domain_add_*() functions - fixed failure to compile - Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c Signed-off-by: Grant Likely Cc: Rob Herring Cc: Benjamin Herrenschmidt Cc: Thomas Gleixner Cc: Milton Miller Tested-by: Olof Johansson

irq_domain/powerpc: Use common irq_domain structure instead of irq_host

2012-02-14T21:06:50+00:00

This patch drops the powerpc-specific irq_host structures and uses the common irq_domain strucutres defined in linux/irqdomain.h. It also fixes all the users to use the new structure names. Renaming irq_host to irq_domain has been discussed for a long time, and this patch is a step in the process of generalizing the powerpc virq code to be usable by all architecture. An astute reader will notice that this patch actually removes the irq_host structure instead of renaming it. This is because the irq_domain structure already exists in include/linux/irqdomain.h and has the needed data members.
