      Pull i2c updates from Wolfram Sang:
       "Quite some driver updates:
         - piix4 can now handle multiplexed adapters
         - brcmstb, xlr, eg20t, designware drivers support more SoCs
         - emev2 gained i2c slave support
         - img-scb and rcar got bigger refactoring to remove issues
         - lots of common driver updates
      
        i2c core changes:
         - new quirk flag when an adapter does not support clock stretching,
           so clients can be configured to avoid that if possible
         - added a helper function to retrieve timing parameters from firmware
           (with rcar being the first user)
         - "multi-master" DT binding added so drivers can adapt to this
           setting (like disabling PM to keep arbitration working)
         - RuntimePM for the logical adapter device is now always enabled by
           the core to ensure propagation from childs to the parent (the HW
           device)
         - new macro builtin_i2c_driver to reduce boilerplate"

      dt-bindings: regulator/clock/mfd: Reorganize S2MPS-family bindings · a13c7c51
      Krzysztof Kozlowski authored
      Bindings for Samsung S2M and S5M family PMICs are in mess. They are
      spread over different files and subdirectories in a non-consistent way.
      The devices and respective drivers for them share a lot in common so
      everything could be organized in a more readable way.
      
      Reorganize the S2MPS11/13/14/15 Device Tree bindings to match the
      drivers for this family of devices:
       - move mfd/s2mps11.txt to mfd/samsung,sec-core.txt for the main MFD
         driver (common for entire family),
       - split clock block to clock/samsung,s2mps11.txt,
       - split regulator block to regulator/samsung,s2mps11.txt.

      As we want gpio_chip .get() calls to be able to return negative
      error codes and propagate to drivers, we need to go over all
      drivers and make sure their return values are clamped to [0,1].
      We do this by using the ret = !!(val) design pattern.

      This also start to propagate the negative error code from the
      smbus call if there is one, as the last commit of this series
      will make the gpiolib core deal with that properly.

       "There's not a lot in this - the main addition is the CRC validation of
        the entire region of the log that the will be recovered, along with
        several log recovery fixes.  Most of the rest is small bug fixes and
        cleanups.
      
        I have three bug fixes still pending, all that address recently fixed
        regressions that I will send to next week after they've had some time
        in for-next.
      
        Summary:
         - extensive CRC validation during log recovery
         - several log recovery bug fixes
         - Various DAX support fixes
         - AGFL size calculation fix
         - various cleanups in preparation for new functionality
         - project quota ENOSPC notification via netlink

       "This series adds two ioctls to control cached data and fragmented
        files.  Most of the rest fixes missing error cases and bugs that we
        have not covered so far.  Summary:
      
        Enhancements:
         - support an ioctl to execute online file defragmentation
         - support an ioctl to flush cached data
         - speed up shrinking of extent_cache entries
         - handle broken superblock
         - refector dirty inode management infra
         - revisit f2fs_map_blocks to handle more cases
         - reduce global lock coverage
         - add detecting user's idle time
      
        Major bug fixes:
         - fix data race condition on cached nat entries
         - fix error cases of volatile and atomic writes"
