Hi,
we have a problem with how to define signals to "adi, gpios" in kernel device-tree.
The following configuration does not work for us:
adi,gpios {
#address-cells = <1>;
#size-cells = <0>;
/*
gpio@0 {
reg = <ADRV9002_DGPIO_0>;
adi,signal = <ADRV9002_GPIO_SIGNAL_ORX_ENABLE_1>;
};
gpio@1 {
reg = <ADRV9002_DGPIO_1>;
adi,signal = <ADRV9002_GPIO_SIGNAL_ORX_ENABLE_2>;
};*/
gpio@2 {
reg = <ADRV9002_AGPIO_00>; //Gpio number. Mandatory property in this node.
adi,signal = <ADRV9002_GPIO_SIGNAL_TX1_EXT_FRONTEND_CONTROL>; //Defines the function of this gpio. Valid range from 0 to 19. Mandatory property in this node.
adi,polarity = <0>; //Polarity of the GPIO pin (normal or inverted). 0 - normal, 1 - inverted
adi,master = <2>; //Whether BBIC or ADRV9001 controls this pin. 0 - BBIC, 2 - ADRV9002
};
gpio@3{
reg = <ADRV9002_AGPIO_08>; //Gpio number. Mandatory property in this node.
adi,signal = <ADRV9001_GPIO_SIGNAL_TX2_EXT_FRONTEND_CONTROL>; //Defines the function of this gpio. Valid range from 0 to 19. Mandatory property in this node.
adi,polarity = <0>; //Polarity of the GPIO pin (normal or inverted). 0 - normal, 1 - inverted
adi,master = <2>; //Whether BBIC or ADRV9001 controls this pin. 0 - BBIC, 2 - ADRV9002
};
gpio@4{
reg = <ADRV9002_AGPIO_01>; //Gpio number. Mandatory property in this node.
adi,signal = <ADRV9001_GPIO_SIGNAL_RX1_EXT_FRONTEND_CONTROL>; //Defines the function of this gpio. Valid range from 0 to 19. Mandatory property in this node.
adi,polarity = <0>; //Polarity of the GPIO pin (normal or inverted). 0 - normal, 1 - inverted
adi,master = <2>; //Whether BBIC or ADRV9001 controls this pin. 0 - BBIC, 2 - ADRV9002
};
/*gpio@5{
reg = <ADRV9002_AGPIO_09>; //Gpio number. Mandatory property in this node.
adi,signal = <ADRV9001_GPIO_SIGNAL_RX2_EXT_FRONTEND_CONTROL>; //Defines the function of this gpio. Valid range from 0 to 19. Mandatory property in this node.
adi,polarity = <0>; //Polarity of the GPIO pin (normal or inverted). 0 - normal, 1 - inverted
adi,master = <2>; //Whether BBIC or ADRV9001 controls this pin. 0 - BBIC, 2 - ADRV9002
};*/
};

If we pull the signal TX1_EN it switches between primed and rf_enabled ensm mode correctly but nothing happens on agpio0 pin.
------
Next problem is gpio ADRV9002_AGPIO_09 is commented out in dts because of this error, we don't know why his settings don't work:
Even if I disconnect it from our LNA, initialization still fails.
Any idea?
Thanks, Tom
