Description
I am using the mt7603 chip, which supports 2 receiving and 2 sending, I found that the chip only outputs a set of driving signals to drive the external PA. The other PA enable signal is not output. How to configure the function of the ANTSEL0 ~ ANTSEL5 pins of mt7603 in the driver to enable it to output the enable signal of the external PA or LNA during transmission and reception. I found the relevant configuration in the eeprom configuration of the chip. If only eeprom is configured, the ANTSEL pin still has no signal.

Research direction
Start by tracing the MT7603 driver's EEPROM configuration and ANTSEL0–ANTSEL5 handling. Follow how the transmit and receive paths program these pins for external PA/LNA control. Done means the required enable signals are emitted during both transmission and reception, with the behavior validated against the requested configuration.
