      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes for the v5.14 kernel. Not so
        much going on. No core changes, just drivers.
      
        The most interesting would be that MIPS Ralink is migrating to pin
        control and we have some bindings but not yet code for the Apple M1
        pin controller.
      
        New drivers:
      
         - Last merge window we created a driver for the Ralink RT2880. We are
           now moving the Ralink SoC pin control drivers out of the MIPS
           architecture code and into the pin control subsystem. This concerns
           RT288X, MT7620, RT305X, RT3883 and MT7621.
      
         - Qualcomm SM6125 SoC pin control driver.
      
         - Qualcomm spmi-gpio support for PM7325.
      
         - Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)
      
         - Mediatek MT8365 SoC pin controller.
      
         - New device HID for the AMD GPIO controller.
      
        Improvements:
      
         - Pin bias config support for a slew of Renesas pin controllers.
      
         - Incremental improvements and non-urgent bug fixes to the Renesas
           SoC drivers.
      
         - Implement irq_set_wake on the AMD pin controller so we can wake up
           from external pin events.
      
        Misc:
      
         - Devicetree bindings for the Apple M1 pin controller, we will
           probably see a proper driver for this soon as well"

      Pull clk updates from Stephen Boyd:
       "This round has a diffstat dominated by Qualcomm clk drivers. Honestly
        though that's just a bunch of data so the diffstat reflects that.
        Looking beyond that there's just a bunch of updates all around in
        various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors
        that have a lot of patches in here.
      
        Overall the driver changes look to be mostly enabling more clks and
        non-critical fixes that we could hold until the next merge window.
      
        I'm especially excited about the series from Arnd that graduates
        clkdev to be the only implementation of clk_get() and clk_put().
        That's a good step in the right direction to migreate eveerything over
        to the common clk framework. Now we don't have to worry about clkdev
        specific details, they're just part of the clk API now.
      
        Core:
         - clkdev is now the only option, i.e. clk_get()/clk_put() is
           implemented in only one place in the kernel instead of in
           drivers/clk/clkdev.c and in architectures that want their own
           implementation
      
        New Drivers:
         - Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant
           Clock Jitter Cleaner With Dual Loop PLLs
         - Qualcomm MDM9607 GCC
         - Qualcomm SC8180X display clks
         - Qualcomm SM6125 GCC
         - Qualcomm SM8250 CAMCC (camera)
         - Renesas RZ/G2L SoC
         - Hisilicon hi3559A SoC
      
        Updates:
         - Stop using clock-output-names in ST clk drivers (yay!)
         - Support secure mode of STM32MP1 SoCs
         - Improve clock support for Actions S500 SoC
         - duty cycle setting support on qcom clks
         - Add TI am33xx spread spectrum clock support
         - Use determine_rate() for the Amlogic pll ops instead of
           round_rate()
         - Restrict Amlogic gp0/1 and audio plls range on g12a/sm1
         - Improve Amlogic axg-audio controller error on deferral
         - Add NNA clocks on Amlogic g12a
         - Reduce memory footprint of Rockchip PLL rate tables
         - A fix for the newly added Rockchip rk3568 clk driver
         - Exported clock for the newly added Rockchip video decoder
         - Remove audio ipg clock from i.MX8MP
         - Remove deprecated legacy clock binding for i.MX SCU clock driver
         - Use common clk-imx8qxp for both i.MX8QXP and i.MX8QM
         - Add multiple clocks to clk-imx8qxp driver (enet, hdmi, lcdif,
           audio, parallel interface)
         - Add dedicated clock ops for i.MX paralel interface
         - Different fixes for clocks controlled by ATF on i.MX SoCs
         - Add A53/A72 frequency scaling support i.MX clk-scu driver
         - Add special case for DCSS clock on suspend for i.MX clk-scu driver
         - Add parent save/restore on suspend/resume to i.MX clk-scu driver
         - Skip runtime PM enablement for CPU clocks in i.MX clk-scu driver
         - Remove the sys1_pll/sys2_pll clock gates for i.MX8MQ and their
           bindings
         - Tegra clk driver no longer deasserts resets on clk_enable as it
           gets in the way of certain power-up sequences
         - Fix compile testing for Tegra clk driver
         - One patch to fix a divider on the Allwinner v3s Audio PLL
         - Add support for CPU core clock boost modes on Renesas R-Car Gen3
         - Add ISPCS (Image Signal Processor) clocks on Renesas R-Car V3U
         - Switch SH/R-Mobile and R-Car "DIV6" clocks to .determine_rate() and
           improve support for multiple parents
         - Switch Renesas RZ/N1 divider clocks to .determine_rate()
         - Add ZA2 (Audio Clock Generator) clock on Renesas R-Car D3
         - Convert ar7 to common clk framework
         - Convert ralink to common clk framework"

       - A few small DM kcopyd efficiency improvements.

         changes that culminate with adding zoned append emulation (which is
         required to properly fix DM crypt's zoned support).
      
       - Various DM writecache target changes that improve efficiency. Adds an
         optional "metadata_only" feature that only promotes bios flagged with
         REQ_META. But the most significant improvement is writecache's
         ability to pause writeback, for a confiurable time, if/when the
         working set is larger than the cache (and the cache is full) -- this
         ensures performance is no worse than the slower origin device.

      io_uring: spin in iopoll() only when reqs are in a single queue · 915b3dde
      Hao Xu authored
      We currently spin in iopoll() when requests to be iopolled are for
      same file(device), while one device may have multiple hardware queues.
      given an example:
      
      hw_queue_0     |    hw_queue_1
      req(30us)           req(10us)
      
      If we first spin on iopolling for the hw_queue_0. the avg latency would
      be (30us + 30us) / 2 = 30us. While if we do round robin, the avg
      latency would be (30us + 10us) / 2 = 20us since we reap the request in
      hw_queue_1 in time. So it's better to do spinning only when requests
      are in same hardware queue.

      io_uring: pre-initialise some of req fields · 99ebe4ef
      Pavel Begunkov authored
      Most of requests are allocated from an internal cache, so it's waste of
      time fully initialising them every time. Instead, let's pre-init some of
      the fields we can during initial allocation (e.g. kmalloc(), see
      io_alloc_req()) and keep them valid on request recycling. There are four
      of them in this patch:
      
      ->ctx is always stays the same
      ->link is NULL on free, it's an invariant
      ->result is not even needed to init, just a precaution
      ->async_data we now clean in io_dismantle_req() as it's likely to
         never be allocated.

      io_uring: reduce latency by reissueing the operation · 59b735ae
      Olivier Langlois authored
      It is quite frequent that when an operation fails and returns EAGAIN,
      the data becomes available between that failure and the call to
      vfs_poll() done by io_arm_poll_handler().
      
      Detecting the situation and reissuing the operation is much faster
      than going ahead and push the operation to the io-wq.
      
      Performance improvement testing has been performed with:
      Single thread, 1 TCP connection receiving a 5 Mbps stream, no sqpoll.
      
      4 measurements have been taken:
      1. The time it takes to process a read request when data is already available
      2. The time it takes to process by calling twice io_issue_sqe() after vfs_poll() indicated that data was available
      3. The time it takes to execute io_queue_async_work()
      4. The time it takes to complete a read request asynchronously
      
      2.25% of all the read operations did use the new path.
      
      ready data (baseline)
      avg	3657.94182918628
      min	580
      max	20098
      stddev	1213.15975908162
      
      reissue	completion
      average	7882.67567567568
      min	2316
      max	28811
      stddev	1982.79172973284
      
      insert io-wq time
      average	8983.82276995305
      min	3324
      max	87816
      stddev	2551.60056552038
      
      async time completion
      average	24670.4758861127
      min	10758
      max	102612
      stddev	3483.92416873804
      
      Conclusion:
      On average reissuing the sqe with the patch code is 1.1uSec faster and
      in the worse case scenario 59uSec faster than placing the request on
      io-wq
      
      On average completion time by reissuing the sqe with the patch code is
      16.79uSec faster and in the worse case scenario 73.8uSec faster than
      async completion.
