Subject[PATCH v3 1/2] arm64: dts: rockchip: RockPro64: enable wifi module at sdio0
Date
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.

Use the in-band sdio irq instead of the out-of-band wifi_host_wake_l
signal since the latter is not working reliably on this board (probably
due to it's PCIe WAKE# connection).

Signed-off-by: Soeren Moch <smoch@web.de>
---
changes in v3:
- none
changes in v2:
- add comment about irq in commit message

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