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

…rnel/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" * tag 'staging-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (455 commits) staging: r8188eu: remove unnecessary memset in r8188eu staging: greybus: introduce pwm_ops::apply staging: rts5208: Resolve checkpatch.pl issues. staging: sm750fb: fix naming style staging: fbtft: Consider type of init sequence values in fbtft_init_display() staging: fbtft: Constify buf parameter in fbtft_dbg_hex() staging: mmal-vchiq: clear redundant item named bulk_scratch mips: dts: ralink: add MT7621 SoC staging: r8188eu: remove some unused local ieee80211 macros staging: r8188eu: make rtl8188e_process_phy_info static staging: r8188eu: remove unused function prototype staging: r8188eu: remove three unused receive defines staging: r8188eu: remove unnecessary initializations staging: rtl8192e: Fix spelling mistake "RESQUEST" -> "REQUEST" MAINTAINERS: remove the obsolete file entry for staging in ANDROID DRIVERS staging: r8188eu: proper error handling in rtw_init_drv_sw staging: r8188eu: call _cancel_timer_ex from _rtw_free_recv_priv staging: vt6656: Removed unused variable vt3342_vnt_threshold staging: vt6656: Removed unused variable bb_vga_0 staging: remove ashmem ...

-  The WFxxx chip series can be connected via SPI or via SDIO.
+description: >
+  Support for the Wifi chip WFxxx from Silicon Labs. Currently, the only device
+  from the WFxxx series is the WF200 described here:
+     https://www.silabs.com/documents/public/data-sheets/wf200-datasheet.pdf
 
-  For SDIO':'
+  The WF200 can be connected via SPI or via 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).
+  For SDIO:
 
-    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
+    Declaring the WFxxx chip in device tree is mandatory (usually, the VID/PID is
+    sufficient for the SDIO devices).
+
+    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
