Subject: [PATCH 0/5] wfx: add support for WoWLAN on Silabs WF200

This is the initial support for Wake-on-WLAN of Silicon WF200 chipset. This
version focus on the power management control. For now, the filtering
capabilities of the chip are not exposed. So any multicast frame (= any ARP
request) will wake up the host.

I have this series of patches in my git tree for a while. I hesitated to
send it because the code is based on a proof of concept and I don't have
access to the hardware anymore.

Therefore, this feature is experimental. However, the only way to reach
this code is to run "iw phy phy0 wowlan enable" or explicitly enable it in
/sys. So, I believe it makes sense to merged it in the stable tree. Thus, I
hope some users will be able to report their success (or their failure).

Jérôme Pouiller (5):
  wifi: wfx: align declarations between bus_spi.c and bus_sdio.c
  wifi: wfx: declare support for WoWLAN
  wifi: wfx: allow SPI device to wake up the host
  wifi: wfx: allow SDIO device to wake up the host
  wifi: wfx: allow to enable WoWLAN using NL80211
