Subject: [PATCH] arch: arm64: dts: amlogic: add wifi/bt support to bananapi m5
|
||
|
|
|
||
|
|
The BPI-M5 has an optional RTL8822CS WiFi/BT mezzanine board. Describe
|
||
|
|
the board but mark the sd_emmc_a and uart_A nodes disabled so they can
|
||
|
|
be enabled via overlay or fdtput when the board is connected.
|
||
|
