Patches 1-7 are the patches to support the BCM4359 chipset with SDIO
interface in the linux brcmfmac net-wireless driver, see [1].

So this patch series has 2 parts:
patches 1-7: add support for the wifi chipset in the wireless driver,
this has to go through net-wireless
patch 8: enable the wifi module with this chipset on RockPro64, this patch

If this was confusing, what would be the ideal way to post such series?

Thanks,
Soeren
