Core changes: - Cleanup and simplification of common code to invoke the low level interrupt flow handlers when this invocation requires irqdomain resolution. Add the necessary core infrastructure. - Provide a proper interface for modular PMU drivers to set the interrupt affinity. - Add a request flag which allows to exclude interrupts from spurious interrupt detection. Useful especially for IPI handlers which always return IRQ_HANDLED which turns the spurious interrupt detection into a pointless waste of CPU cycles. Driver changes: - Bulk convert interrupt chip drivers to the new irqdomain low level flow handler invocation mechanism. - Add device tree bindings for the Renesas R-Car M3-W+ SoC - Enable modular build of the Qualcomm PDC driver - The usual small fixes and improvements. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmDbIg8THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYobZNEAC2wTq3Ishk026va7g5mbQVSvAQyf8G 0msmgJ48lJWVL9a6JUogNcCO7sZCTcAy4CYbuHI6kz1fGZZnNWSCrtEz0rFNAdWE WVR2k8ExR2R73vJm+K50WUMMj8YsefRnIFXWlJdTp+pksr3TZ7Lo70taGUK/6tMo aL0dqvnf7Vb3LG0iIkaHWLF4HnyK/UGqB+121rlL4UhI1/g+3EUxNWNcY5eg/dmc Ym73U1uDsjydp3/3jm8v8NYNtwCDGpujZZc/88RFLjP6PMpF1S9JUvDEt+LHJi0a cdS3RreB78HYXpLg5NtDFJwIegRMLSitvCGPBjHvWBzbifkMsA2zWIb6Cs8VkYys vuPoEGZ0ol+SWvcnSh5Xy36nyr4iGIBhQql47UAaqelSxsYPjvCCSD4yJV3k8hnC ZuDscOekXUMn75qZR0quNdi1SkgKpGZxK73QFbuW3Apl5EgArVai6kq0rbl6zlx6 ACy0SEcevhOcpU6WpqDgrmUBgFr+M8zina8edRELgiFEuWT6pYxKwrN3pT4U5djO e5V3YuNzzwzvtUoXN4AiTlT8gwRiGfgeiEvHpvZBXPNvk5ffS6XzPiV81ZMWiBkb ReoCbqME3PKoxj1VAHJvVXHbcjiPIJeCRdV+5vQSNh1SPSQOmEdWyJtNUDrSkoym QkKKY5jrOhPhlQ== =FIKh -----END PGP SIGNATURE----- Merge tag 'irq-core-2021-06-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "Updates for the interrupt subsystem: Core changes: - Cleanup and simplification of common code to invoke the low level interrupt flow handlers when this invocation requires irqdomain resolution.
