Merge tag 'staging-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 

Pull staging driver updates from Greg KH:
 "Here is the big set of staging driver updates for 5.18-rc1.

  Loads of tiny cleanups for almost all staging drivers in here, nothing
  major at all. Highlights include:

   - remove the ashmem Android driver. It is long-dead and if there are
     any legacy userspace applications still using it, the Android
     kernel images will maintain it, the community shouldn't care about
     it anymore

   - wfx wifi driver major cleanups. Should be ready to merge out of
     staging soon, and will coordinate with the wifi maintainers after
     -rc1 is out

   - major cleanups and unwinding of the layers of the r8188eu driver.
     It's amazing just how many unneeded layers of abstraction is in
     there, just when we think it's done, another is found...

   - lots of tiny coding style cleanups in many other staging drivers.

  All have been in linux-next for a while with no reported problems"

  Support for the Wifi chip WFxxx from Silicon Labs. Currently, the only device

  from the WFxxx series is the WF200 described here:

  The WF200 can be connected via SPI or via SDIO.



  For SDIO':'

  For SDIO:



    The driver is able to detect a WFxxx chip on SDIO bus by matching its Vendor

    ID and Product ID. However, driver will only provide limited features in

    this case. Thus declaring WFxxx chip in device tree is recommended (and may

    become mandatory in the future).

    Declaring the WFxxx chip in device tree is mandatory (usually, the VID/PID is

    sufficient for the SDIO devices).



    In addition, it is recommended to declare a mmc-pwrseq on SDIO host above

    WFx. Without it, you may encounter issues with warm boot. The mmc-pwrseq

    should be compatible with mmc-pwrseq-simple. Please consult

    It is recommended to declare a mmc-pwrseq on SDIO host above WFx. Without

    it, you may encounter issues during reboot. The mmc-pwrseq should be
