      MIPS: qi_lb60: Migrate to devicetree · 8ddebad1
      Paul Cercueil authored
      Move all the platform data to devicetree.
      
      The only bit dropped is the PWM beeper, which requires the PWM driver
      to be updated. I figured it's okay to remove it here since it's really
      a non-critical device, and it'll be re-introduced soon enough.
      
      The other change is the CS line of the SPI is now set as active low. The
      SPI core would have forced "active low" anyway, unless the 'spi-cs-high'
      property is set.
      
      In the process of moving to devicetree, we also switched to new drivers:
      - We use the simple-audio-card and simple-amplifier drivers instead of
        the custom ASoC code;
      - We use the new Ingenic DRM driver coupled with the GiantPlus GPM940B0
        DRM panel driver instead of the old framebuffer driver;
      - We use the new jz4780-dma driver instead of the old jz4740-dma one;
      - We use the ingenic-nand and jz4740-ecc drivers instead of the old
        jz4740-nand driver;
      - We use ingenic-battery instead of jz4740-battery;
      - We use iio-hwmon instead of jz4740-hwmon;
      - We use ingenic-iio instead of the old jz4740-adc MFD driver.

      MIPS: BCM47XX: Add support for Netgear R6200 V1 · 42374b94
      Edward Matijević authored
      The Netgear R6200 v1 uses a BCM4718A1 SOC and a BCM4352/BCM4360 for 5GHz
      wireless. This patch adds support for detecting this model board and
      registers the 3 buttons.
      
      I have tested that the device can boot kernels 4.14 and 4.19 under
      OpenWRT.
      
      There is one issue that the LEDs on the device are controlled by a
      74HC164 that uses bit-banging instead of SPI so it isn't accessible to
      the kernel without adding a workaround. Without any workaround the
      device on boot will flash all LEDs once then the power LED will remain
      amber as all other LEDs stay off.

      mips: Add clock_gettime64 entry point · 1f66c45d
      Vincenzo Frascino authored
      With the release of Linux 5.1 has been added a new syscall,
      clock_gettime64, that provided a 64 bit time value for a specified
      clock_ID to make the kernel Y2038 safe on 32 bit architectures.
      
      Update the mips32 specific vDSO library accordingly with what it has
      been done for the kernel syscall exposing the clock_gettime64 entry
      point.

      MIPS: Undefine PMD_ORDER for 32-bit builds · 7176b6ac
      Daniel Silsby authored
      During an update long ago to conform to 4-level page code, PMD_ORDER was
      changed from 0 to 1, despite the fact that a PMD table is not used at
      all in a 32-bit MIPS build. PMD_ORDER does not seem to be used in these
      builds. Now, it matches PUD_ORDER, a nonsense #define to give a build
      failure with informative error.
      
      The older commit that had redefined PMD_ORDER was
      commit c6e8b587 ("Update MIPS to use the 4-level pagetable code

       This adds initial support for huge pages to 32-bit MIPS systems.
      Systems with extended addressing enabled (EVA,XPA,Alchemy/Netlogic)

       With huge pages enabled, this implementation will increase page table

      MIPS: Disallow CPU_SUPPORTS_HUGEPAGES for XPA,EVA · 171543e7
      Daniel Silsby authored
      In preparation for 32-bit MIPS huge page support.
      
      EVA,XPA are extended-addressing modes for 32-bit MIPS systems. Because
      huge pages aren't currently supported in 32-bit MIPS, this doesn't take
      any features away from EVA,XPA-enabled systems. However, the soon-to-
      come 32-bit MIPS huge page support doesn't yet support them.
      
      This also disables CPU_SUPPORTS_HUGEPAGES for the small number of 32-bit
      MIPS CPUs from Alchemy/Netlogic that support a custom 36-bit extended
      addressing. It's unknown if they even support huge pages in hardware.

      iommu/amd: fix a crash in iova_magazine_free_pfns · 8cf66504
      Qian Cai authored
      The commit b3aa14f0 ("iommu: remove the mapping_error dma_map_ops
      method") incorrectly changed the checking from dma_ops_alloc_iova() in
      map_sg() causes a crash under memory pressure as dma_ops_alloc_iova()
      never return DMA_MAPPING_ERROR on failure but 0, so the error handling
      is all wrong.

      The hexagon implementation pte_alloc_one(), pte_alloc_one_kernel(),
      pte_free_kernel() and pte_free() is identical to the generic except of
      lack of __GFP_ACCOUNT for the user PTEs allocation.
      
      Switch hexagon to use generic version of these functions.

      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.

      dt-bindings: Ensure child nodes are of type 'object' · 15ffef1a
      Rob Herring authored
      Properties which are child node definitions need to have an explict
      type. Otherwise, a matching (DT) property can silently match when an
      error is desired. Fix this up tree-wide. Once this is fixed, the
      meta-schema will enforce this on any child node definitions.
