Merge tag 'i3c/for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux
Pull i3c updates from Alexandre Belloni: "There are now more fixes because as stated in my previous pull request, people now have access to actual hardware. Core: - handle IBI in the proper order Drivers: - cdns: fix status register access - mipi-i3c-hci: many fixes now that the driver has been actually tested - svc: many IBI fixes, correct compatible string, fix hot join corner cases" * tag 'i3c/for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux: (29 commits) i3c: master: handle IBIs in order they came i3c: master: mipi-i3c-hci: Fix a kernel panic for accessing DAT_data. i3c: master: svc: fix compatibility string mismatch with binding doc i3c: master: svc: fix random hot join failure since timeout error i3c: master: svc: fix SDA keep low when polling IBIWON timeout happen i3c: master: svc: fix check wrong status register in irq handler i3c: master: svc: fix ibi may not return mandatory data byte i3c: master: svc: fix wrong data return when IBI happen during start frame i3c: master: svc: fix race condition in ibi work thread i3c: Fix typo "Provisional ID" to "Provisioned ID" i3c: Fix potential refcount leak in i3c_master_register_new_i3c_devs i3c: mipi-i3c-hci: Resume controller after aborted transfer i3c: mipi-i3c-hci: Resume controller explicitly i3c: mipi-i3c-hci: Fix missing xfer->completion in hci_cmd_v1_daa() i3c: mipi-i3c-hci: Do not unmap region not mapped for transfer i3c: mipi-i3c-hci: Set number of SW enabled Ring Bundles earlier i3c: mipi-i3c-hci: Fix race between bus cleanup and interrupt i3c: mipi-i3c-hci: Set ring start request together with enable i3c: mipi-i3c-hci: Remove BUG() when Ring Abort request times out i3c: mipi-i3c-hci: Fix out of bounds access in hci_dma_irq_handler ...
