The Front End Module(FEM) normally includes tx power amplifier(PA) and rx low noise amplifier(LNA). The default timing parameters like tx end to PA off timing values were fine tuned for internal FEM used in reference design. And these timing values can not be same if ODM modifies hardware design with different external FEM. This DT entry helps to choose correct timing values in driver if different external FEM hardware used.
