      Pull IOMMU updates from Joerg Roedel:
       - ATS support for ARM-SMMU-v3.
       - AUX domain support in the IOMMU-API and the Intel VT-d driver. This
         adds support for multiple DMA address spaces per (PCI-)device. The
         use-case is to multiplex devices between host and KVM guests in a
         more flexible way than supported by SR-IOV.
       - the rest are smaller cleanups and fixes, two of which needed to be
         reverted after testing in linux-next.

      Merge tag 'gpio-v5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio · 8148c17b
      Linus Torvalds authored
      Pull gpio updates from Linus Walleij:
       "This is the bulk of the GPIO changes for the v5.2 kernel cycle. A bit
        later than usual because I was ironing out my own mistakes. I'm
        holding some stuff back for the next kernel as a result, and this
        should be a healthy and well tested batch.
        Core changes:
         - The gpiolib MMIO driver has been enhanced to handle two direction
           registers, i.e. one register to set lines as input and one register
           to set lines as output. It turns out some silicon engineer thinks
           the ability to configure a line as input and output at the same
           time makes sense, this can be debated but includes a lot of analog
           electronics reasoning, and the registers are there and need to be
           handled consistently. Unsurprisingly, we enforce the lines to be
           either inputs or outputs in such schemes.
         - Send in the proper argument value to .set_config() dispatched to
           the pin control subsystem. Nobody used it before, now someone does,
           so fix it to work as expected.
         - The ACPI gpiolib portions can now handle pin bias setting (pull up
           or pull down). This has been in the ACPI spec for years and we
           finally have it properly integrated with Linux GPIOs. It was based
           on an observation from Andy Schevchenko that Thomas Petazzoni's
           changes to the core for biasing the PCA950x GPIO expander actually
           happen to fit hand-in-glove with what the ACPI core needed. Such
           nice synergies happen sometimes.
        New drivers:
         - A new driver for the Mellanox BlueField GPIO controller. This is
           using 64bit MMIO registers and can configure lines as inputs and
           outputs at the same time and after improving the MMIO library we
           handle it just fine. Interesting.
         - A new IXP4xx proper gpiochip driver with hierarchical interrupts
           should be coming in from the ARM SoC tree as well.
        Driver enhancements:
         - The PCA053x driver handles the CAT9554 GPIO expander.
         - The PCA053x driver handles the NXP PCAL6416 GPIO expander.
         - Wake-up support on PCA053x GPIO lines.
         - OMAP now does a nice asynchronous IRQ handling on wake-ups by
           letting everything wake up on edges, and this makes runtime PM work
           as expected too.
         - Several cleanups such as devres fixes.
         - Get rid of some languager comstructs that cause problems when
           compiling with LLVMs clang.
         - Documentation review and update"
