      gpio: ixp4xx: Convert to hierarchical GPIOLIB_IRQCHIP · aa7d618a
      Linus Walleij authored
      This modifies the IXP4xx driver to use the new helpers
      to handle the remapping of parent to child hardware irqs
      in the gpiolib core.
      
      This pulls the majority of the code out of the driver
      and use the generic code in gpiolib.

      gpio: Add support for hierarchical IRQ domains · fdd61a01
      Linus Walleij authored
      Hierarchical IRQ domains can be used to stack different IRQ
      controllers on top of each other.
      
      Bring hierarchical IRQ domains into the GPIOLIB core with the
      following basic idea:
      
      Drivers that need their interrupts handled hierarchically
      specify a callback to translate the child hardware IRQ and
      IRQ type for each GPIO offset to a parent hardware IRQ and
      parent hardware IRQ type.
      
      Users have to pass the callback, fwnode, and parent irqdomain
      before calling gpiochip_irqchip_add().
      
      We use the new method of just filling in the struct
      gpio_irq_chip before adding the gpiochip for all hierarchical
      irqchips of this type.
      
      The code path for device tree is pretty straight-forward,
      while the code path for old boardfiles or anything else will
      be more convoluted requireing upfront allocation of the
      interrupts when adding the chip.
      
      One specific use-case where this can be useful is if a power
      management controller has top-level controls for wakeup
      interrupts. In such cases, the power management controller can
      be a parent to other interrupt controllers and program
      additional registers when an IRQ has its wake capability
      enabled or disabled.
      
      The hierarchical irqchip helper code will only be available
      when IRQ_DOMAIN_HIERARCHY is selected to GPIO chips using
      this should select or depend on that symbol. When using
      hierarchical IRQs, the parent interrupt controller must
      also be hierarchical all the way up to the top interrupt
      controller wireing directly into the CPU, so on systems
      that do not have this we can get rid of all the extra
      code for supporting hierarchical irqs.

      The commit b3aa14f0 ("iommu: remove the mapping_error dma_map_ops

      dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodes · 7d9ef7f3
      Rob Herring authored
      Matching on the 'cpus' node was a bad choice because the schema is
      incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
      schema which checks the general structure, it is also redundant to do so
      in the Risc-V CPU schema.
      
      The downside is one could conceivably mix different architecture's cpu
      nodes or have typos in the compatible string. The latter problem pretty
      much exists for every schema.

      Pull dma-mapping fixes from Christoph Hellwig:
       "Fix various regressions:
      
         - force unencrypted dma-coherent buffers if encryption bit can't fit
           into the dma coherent mask (Tom Lendacky)
      
         - avoid limiting request size if swiotlb is not used (me)
      
         - fix swiotlb handling in dma_direct_sync_sg_for_cpu/device (Fugang
           Duan)"

        dma-direct: correct the physical addr in dma_direct_sync_sg_for_cpu/device

      Pull x86 fixes from Thomas Gleixner:
       "A set of x86 specific fixes and updates:
      
         - The CR2 corruption fixes which store CR2 early in the entry code
           and hand the stored address to the fault handlers.
      
         - Revert a forgotten leftover of the dropped FSGSBASE series.
      
         - Plug a memory leak in the boot code.
      
         - Make the Hyper-V assist functionality robust by zeroing the shadow
           page.
      
         - Remove a useless check for dead processes with LDT
      
         - Update paravirt and VMware maintainers entries.
      
         - A few cleanup patches addressing various compiler warnings"
