Subject: [PATCH] dts: Add noanthogs parameter to CM4 and CM5
|
|
|
|
By default, the antenna selection on CM4 and CM5 is fixed at boot time,
|
|
with the dtparams ant1, ant2 and noant selecting which should be
|
|
enabled. Add a new dtparam - noanthogs - which leaves the GPIOs free
|
|
to be controlled at runtime by the OS.
|
|
|
|
N.B. Using this parameter without suitable OS support will leave both
|
|
antennae disabled, resulting in attenuated WiFi and Bluetooth signals.
