Reset controller updates for v6.11 Move reset controller registration to the end in rzg2l-usbphy-ctrl, to simplify the probe error path, add a new i.MX8MP AudioMix reset driver, allow to build some drivers under COMPILE_TEST with fewer dependencies, and use the devm_clk_get_enabled convenience wrapper in meson-audio-arb. The latter causes a trivial merge conflict [1] with b99e9c09 ("reset: meson-audio-arb: Convert to platform remove callback returning void") because I didn't manage to send that in last round.

Merge tag 'ffa-updates-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A driver updates for v6.11 The main addition is the split of bus and driver into distinct modules The FF-A bus module is initialized at subsys_initcall level when builtin. FF-A drivers initialization is now changed to module_init level so that pKVM ffa proxy is all setup and running in case pKVM hypervisor needs to trap and handle FF-A calls. One of the reason for not having this split from the beginning is the need to workaround the FF-A v1.0 NULL UUID. The FF-A bus layer called into FF-A driver and populated the device UUID if it matches with the driver attempting to match. Moving the workaround away from the FF-A bus layer to the FF-A core driver as a bus notifier will help to remove the dependency. * tag 'ffa-updates-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Split bus and driver into distinct modules firmware: arm_ffa: Move the FF-A v1.0 NULL UUID workaround to bus notifier Link: https://lore.kernel.org/r/20240624103451.2870146-1-sudeep.holla@arm.comSigned-off-by: Arnd Bergmann <arnd@arndb.de>

Merge tag 'scmi-updates-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI driver updates for v6.11 The main addition this time is the support for platform to agent(p2a also referred sometimes as notification or Rx) channel completion via interrupt driven method. Currently, the OSPM agent clears or acknowledge the receipt of the norification or delayed response by updating the flags in the shared memory region which the platform is expected to poll. On some platforms that are completely interrupt driven, the OSPM agent is expected to send a response message instead. This change adds the support for the same. Other changes include addition of a separate mailing list specific to SCMI to allow open discussions about the interface itself in addition to the kernel driver updates and support for system suspend via the platform noification used on some systems. * tag 'scmi-updates-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Add support for platform to agent channel completion dt-bindings: firmware: arm,scmi: Add support for notification completion channel firmware: arm_scmi: Add support for system suspend in power control driver MAINTAINERS: Add mailing list for SCMI drivers Link: https://lore.kernel.org/r/20240620093924.375244-3-sudeep.holla@arm.comSigned-off-by: Arnd Bergmann <arnd@arndb.de>

Pull bcachefs fixes from Kent Overstreet: "Lots of (mostly boring) fixes for syzbot bugs and rare(r) CI bugs. The LRU_TIME_BITS fix was slightly more involved; we only have 48 bits for the LRU position (we would prefer 64), so wraparound is possible for the cached data LRUs on a filesystem that has done sufficient (petabytes) reads; this is now handled. One notable user reported bugfix, where we were forgetting to correctly set the bucket data type, which should have been BCH_DATA_need_gc_gens instead of BCH_DATA_free; this was causing us to go emergency read-only on a filesystem that had seen heavy enough use to see bucket gen wraparoud. We're now starting to fix simple (safe) errors without requiring user intervention - i.e. a small incremental step towards full self healing.

Pull kvm fixes from Paolo Bonzini: "ARM: - Fix dangling references to a redistributor region if the vgic was prematurely destroyed. - Properly mark FFA buffers as released, ensuring that both parties can make forward progress. x86: - Allow getting/setting MSRs for SEV-ES guests, if they're using the pre-6.9 KVM_SEV_ES_INIT API. - Always sync pending posted interrupts to the IRR prior to IOAPIC route updates, so that EOIs are intercepted properly if the old routing table requested that. Generic: - Avoid __fls(0) - Fix reference leak on hwpoisoned page - Fix a race in kvm_vcpu_on_spin() by ensuring loads and stores are atomic. - Fix bug in __kvm_handle_hva_range() where KVM calls a function pointer that was intended to be a marker only (nothing bad happens but kind of a mine and also technically undefined behavior) - Do not bother accounting allocations that are small and freed before getting back to userspace. Selftests: - Fix compilation for RISC-V. - Fix a "shift too big" goof in the KVM_SEV_INIT2 selftest. - Compute the max mappable gfn for KVM selftests on x86 using GuestMaxPhyAddr from KVM's supported CPUID (if it's available)" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: SEV-ES: Fix svm_get_msr()/svm_set_msr() for KVM_SEV_ES_INIT guests KVM: Discard zero mask with function kvm_dirty_ring_reset virt: guest_memfd: fix reference leak on hwpoisoned page kvm: do not account temporary allocations to kmem MAINTAINERS: Drop Wanpeng Li as a Reviewer for KVM Paravirt support KVM: x86: Always sync PIR to IRR prior to scanning I/O APIC routes KVM: Stop processing *all* memslots when "null" mmu_notifier handler is found KVM: arm64: FFA: Release hyp rx buffer KVM: selftests: Fix RISC-V compilation KVM: arm64: Disassociate vcpus from redistributor region on teardown KVM: Fix a data race on last_boosted_vcpu in kvm_vcpu_on_spin() KVM: selftests: x86: Prioritize getting max_gfn from GuestPhysBits KVM: selftests: Fix shift of 32 bit unsigned int more than 32 bits

"Failed to lock the clock" is an appropriate error message for clk_rate_exclusive_get() failing, but not for the clock running too fast for the driver's calculations. Adapt the error message accordingly.

A small prescaler is beneficial, as this improves the resolution of the duty_cycle configuration. However if the prescaler is too small, the maximal possible period becomes considerably smaller than the requested value. One situation where this goes wrong is the following: With a parent clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for period = 941243 ns currently results in PSC = 1. The value for ARR is then calculated to ARR = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301 This value is bigger than 65535 however and so doesn't fit into the respective register field. In this particular case the PWM was configured for a period of 313733.4806027616 ns (with ARR = 98301 & 0xffff). Even if ARR was configured to its maximal value, only period = 627495.6861167669 ns would be achievable. Fix the calculation accordingly and adapt the comment to match the new algorithm. With the calculation fixed the above case results in PSC = 2 and so an actual period of 941229.1667195285 ns.
