[ncs 2.7.0] Simple GPIO to control SKY85303 FEM

[Gavin]

Hi，

I have a custom board with nRF52833 and sky85303-21 FEM. To control the FEM, I have added the following code to my app.overlay file and enabled simple GPIO configs.

/ {
    nrf_radio_fem: name_of_fem_node {
       compatible = "skyworks,sky66112-11", "generic-fem-two-ctrl-pins";
       ctx-gpios = <&gpio0 3 GPIO_ACTIVE_HIGH>;
       crx-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;
    };
 };
 

CONFIG_MPSL=y
CONFIG_MPSL_FEM_ONLY=y
# CONFIG_MPSL_FEM_LOG_LEVEL_DBG=y
CONFIG_MPSL_FEM_SIMPLE_GPIO=y
CONFIG_GPIO=y

Build issue:

I’m not sure if there are any other configurations that need to be enabled. Could you please advise if there are additional settings I should be aware of?

My question:

I noticed that the documentation primarily discusses the SKY66112-11. I wanted to confirm whether I can use this directly, or if I need to develop a separate driver for the SKY85303-21.

Thanks,

Gavin
