[PATCH 8/8] arm64: dts: rockchip: RockPro64: enable wifi module at sdio0

From: Soeren Moch
Date: Mon Dec 09 2019 - 17:38:52 EST


RockPro64 supports an Ampak AP6359SA based wifi/bt combo module.
The BCM4359/9 wifi controller in this module is connected to sdio0,
enable this interface.

Not sure where to place exactly the sdio0 node in the dts because
existing sd nodes are not sorted alphabetically.

This last patch in this brcmfmac patch series probably should be picked
up by Heiko independently of the rest of this series. It was sent together
to show how this brcmfmac extension for 4359-sdio support with RSDB is
used and tested.
