Most irq_domain_add_*() functions are unused now, so drop them. The remaining ones are moved to the deprecated section and will be removed during the merge window after the patches in various trees have been merged. Note: The Chinese docs are touched but unfinished. I cannot parse those.

2025-05-16powerpc: Switch irq_domain_add_nomap() to use fwnodeJiri Slaby (SUSE)2-2/+2
All irq_domain_add_*() functions are going away. PowerPC is the only user of irq_domain_add_nomap() and there is no irq_domain_create_nomap() complement. Therefore, to align with the rest of the kernel, rename irq_domain_add_nomap() to irq_domain_create_nomap() and accept a fwnode_handle instead of a device_node.

2025-05-16rcutorture: Perform more frequent testing of ->gpwrapJoel Fernandes1-0/+25
Currently, the ->gpwrap is not tested (at all per my testing) due to the requirement of a large delta between a CPU's rdp->gp_seq and its node's rnp->gpseq. This results in no testing of ->gpwrap being set. This patch by default adds 5 minutes of testing with ->gpwrap forced by lowering the delta between rdp->gp_seq and rnp->gp_seq to just 8 GPs. All of this is configurable, including the active time for the setting and a full testing cycle. By default, the first 25 minutes of a test will have the _default_ behavior there is right now (ULONG_MAX / 4) delta. Then for 5 minutes, we switch to a smaller delta causing 1-2 wraps in 5 minutes. I believe this is reasonable since we at least add a little bit of testing for usecases where ->gpwrap is set.

PolarFire SoC may be configured in a way that requires non-coherent DMA handling. On RISC-V, buses are coherent by default & the dma-noncoherent property is required to denote buses or devices that are non-coherent. For some reason, instead of adding dma-noncoherent to the binding the pointless, NOP, property dma-coherent was. Swap dma-coherent for dma-noncoherent.

Document support for the Renesas OS Timer (OSTM) found on the Renesas RZ/V2N (R9A09G056) SoC. The OSTM IP on RZ/V2N is identical to that on other RZ families, so no driver changes are required as `renesas,ostm` will be used as fallback compatible. Also update the bindings to require the "resets" property for RZ/V2N by inverting the logic: all SoCs except RZ/A1 and RZ/A2 now require the "resets" property.

2025-05-16vsprintf: remove redundant and unused %pCn format specifierLuca Ceresoli2-4/+2
%pC and %pCn print the same string, and commit 900cca294425 ("lib/vsprintf: add %pC{,n,r} format specifiers for clocks") introducing them does not clarify any intended difference. It can be assumed %pC is a default for %pCn as some other specifiers do, but not all are consistent with this policy. Moreover there is now no other suffix other than 'n', which makes a default not really useful. All users in the kernel were using %pC except for one which has been converted. So now remove %pCn and all the unnecessary extra code and documentation.
