      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.20 series:
      
        Core changes:
      
         - A patch series from Hans Verkuil to make it possible to
           enable/disable IRQs on a GPIO line at runtime and drive GPIO lines
           as output without having to put/get them from scratch.
      
           The irqchip callbacks have been improved so that they can use only
           the fastpatch callbacks to enable/disable irqs like any normal
           irqchip, especially the gpiod_lock_as_irq() has been improved to be
           callable in fastpath context.
      
           A bunch of rework had to be done to achieve this but it is a big
           win since I never liked to restrict this to slowpath. The only call
           requireing slowpath was try_module_get() and this is kept at the
           .request_resources() slowpath callback. In the GPIO CEC driver this
           is a big win sine a single line is used for both outgoing and
           incoming traffic, and this needs to use IRQs for incoming traffic
           while actively driving the line for outgoing traffic.
      
         - Janusz Krzysztofik improved the GPIO array API to pass a "cookie"
           (struct gpio_array) and a bitmap for setting or getting multiple
           GPIO lines at once.
      
           This improvement orginated in a specific need to speed up an OMAP1
           driver and has led to a much better API and real performance gains
           when the state of the array can be used to bypass a lot of checks
           and code when we want things to go really fast.
      
           The previous code would minimize the number of calls down to the
           driver callbacks assuming the CPU speed was orders of magnitude
           faster than the I/O latency, but this assumption was wrong on
           several platforms: what we needed to do was to profile and improve
           the speed on the hot path of the array functions and this change is
           now completed.
      
         - Clean out the painful and hard to grasp BNF experiments from the
           device tree bindings. Future approaches are looking into using JSON
           schema for this purpose. (Rob Herring is floating a patch series.)
      
        New drivers:
      
         - The RCAR driver now supports r8a774a1 (RZ/G2M).
      
         - Synopsys GPIO via CREGs driver.
      
        Major improvements:
      
         - Modernization of the EP93xx driver to use irqdomain and other
           contemporary concepts.
      
         - The ingenic driver has been merged into the Ingenic pin control
           driver and removed from the GPIO subsystem.
      
         - Debounce support in the ftgpio010 driver"

      Pull regmap updates from Mark Brown:
       "A small update with a couple of new APIs that are useful for some
        small sets of devices:
      
         - Split up the single_rw flagging to map read and write separately as
           some devices support bulk operations for only read or only write.
      
         - Add a write version of the noinc API.
      
         - Clean up the code for LOG_DEVICE a bit"
      
      * tag 'regmap-v5.0' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
        regmap: use less #ifdef for LOG_DEVICE
        regmap: Add regmap_noinc_write API
        regmap: split up regmap_config.use_single_rw
        regmap: fix comment for regmap.use_single_write

      Pull mtd updates from Boris Brezillon:
       "SPI NOR core changes:
         - Support non-uniform erase size
         - Support controllers with limited TX fifo size
      
       Driver changes:
         - m25p80: Re-issue a WREN command after each write access
         - cadence: Pass a proper dir value to dma_[un]map_single()
         - fsl-qspi: Check fsl_qspi_get_seqid() return val make sure 4B
           addressing opcodes are properly handled
         - intel-spi: Add a new PCI entry for Ice Lake
      
       Raw NAND core changes:
         - Two batchs of cleanups of the NAND API, including:
            * Deprecating a lot of interfaces (now replaced by ->exec_op()).
            * Moving code in separate drivers (JEDEC, ONFI), in private files
              (internals), in platform drivers, etc.
            * Functions/structures reordering.
            * Exclusive use of the nand_chip structure instead of the MTD one
              all across the subsystem.
         - Addition of the nand_wait_readrdy/rdy_op() helpers.
      
       Raw NAND controllers drivers changes:
         - Various coccinelle patches.
         - Marvell:
            * Use regmap_update_bits() for syscon access.
            * More documentation.
            * BCH failure path rework.
            * More layouts to be supported.
            * IRQ handler complete() condition fixed.
         - Fsl_ifc:
            * SRAM initialization fixed for newer controller versions.
         - Denali:
            * Fix licenses mismatch and use a SPDX tag.
            * Set SPARE_AREA_SKIP_BYTES register to 8 if unset.
         - Qualcomm:
            * Do not include dma-direct.h.
         - Docg4:
            * Removed.
         - Ams-delta:
            * Use of a GPIO lookup table
            * Internal machinery changes.
      
       Raw NAND chip drivers changes:
         - Toshiba:
            * Add support for Toshiba memory BENAND
            * Pass a single nand_chip object to the status helper.
         - ESMT:
            * New driver to retrieve the ECC requirements from the 5th ID
              byte.
