Hi,

Thank you for your patch!

From: Christian Stefan Kövér-Draxl<ckoever@xxxxxxxxxx>

The RF configuration selects the single antenna setting only for parts
flagged as coexistence capable. On an S905W2 TV box with a W155S2-class
W1 chip, Bluetooth and Wi-Fi share one antenna; with the default dual
antenna setting the received signal is about 15 dB weaker.

Use the single antenna setting when the board sets
amlogic,shared-antenna.
