The A53 CCM clk root only accepts input up to 1GHz, CCM A53 root signoff timing is 1Ghz, however the A53 core which sources from CCM root could run above 1GHz which voilates the CCM.

There are several clock slices, current composite code only support bus/ip clock slices, it could not support core slice. So introduce a new API imx8m_clk_hw_composite_core to support core slice. To core slice, post divider with 3 bits width and no pre divider. Other fields are same as bus/ip slices. Add a flag IMX_COMPOSITE_CORE for the usecase. Reviewed-by:

Pull new zonefs file system from Damien Le Moal: "Zonefs is a very simple file system exposing each zone of a zoned block device as a file. Unlike a regular file system with native zoned block device support (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the sequential write constraint of zoned block devices to the user. As a result, zonefs is not a POSIX compliant file system. Its goal is to simplify the implementation of zoned block devices support in applications by replacing raw block device file accesses with a richer file based API, avoiding relying on direct block device file ioctls which may be more obscure to developers. One example of this approach is the implementation of LSM (log-structured merge) tree structures (such as used in RocksDB and LevelDB) on zoned block devices by allowing SSTables to be stored in a zone file similarly to a regular file system rather than as a range of sectors of a zoned device. The introduction of the higher level construct "one file is one zone" can help reducing the amount of changes needed in the application while at the same time allowing the use of zoned block devices with various programming languages other than C. Zonefs IO management implementation uses the new iomap generic code. Zonefs has been successfully tested using a functional test suite (available with zonefs userland format tool on github) and a prototype implementation of LevelDB on top of zonefs" * tag 'zonefs-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs: zonefs: Add documentation fs: New zonefs file system

Pull x86 fixes from Thomas Gleixner: "A set of fixes for X86: - Ensure that the PIT is set up when the local APIC is disable or configured in legacy mode. This is caused by an ordering issue introduced in the recent changes which skip PIT initialization when the TSC and APIC frequencies are already known. - Handle malformed SRAT tables during early ACPI parsing which caused an infinite loop anda boot hang. - Fix a long standing race in the affinity setting code which affects PCI devices with non-maskable MSI interrupts. The problem is caused by the non-atomic writes of the MSI address (destination APIC id) and data (vector) fields which the device uses to construct the MSI message. The non-atomic writes are mandated by PCI. If both fields change and the device raises an interrupt after writing address and before writing data, then the MSI block constructs a inconsistent message which causes interrupts to be lost and subsequent malfunction of the device. The fix is to redirect the interrupt to the new vector on the current CPU first and then switch it over to the new target CPU. This allows to observe an eventually raised interrupt in the transitional stage (old CPU, new vector) to be observed in the APIC IRR and retriggered on the new target CPU and the new vector. The potential spurious interrupts caused by this are harmless and can in the worst case expose a buggy driver (all handlers have to be able to deal with spurious interrupts as they can and do happen for various reasons). - Add the missing suspend/resume mechanism for the HYPERV hypercall page which prevents resume hibernation on HYPERV guests. This change got lost before the merge window. - Mask the IOAPIC before disabling the local APIC to prevent potentially stale IOAPIC remote IRR bits which cause stale interrupt lines after resume" * tag 'x86-urgent-2020-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/apic: Mask IOAPIC entries when disabling the local APIC x86/hyperv: Suspend/resume the hypercall page for hibernation x86/apic/msi: Plug non-maskable MSI affinity race x86/boot: Handle malformed SRAT tables during early ACPI parsing x86/timer: Don't skip PIT setup when APIC is disabled or in legacy mode -
