Subject: [PATCH 119/120] WIP: arm64: dts: meson: 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_mmc_a and uart_A nodes disabled so they can
|
|
be enabled via overlay or fdtput when the baord is connected.
