| |
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 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.
