I have an out-of-tree driver. It has an I2C that is working but also GPIO that are only working with compatible = "gpio-leds" but not with the driver compatible = "st,vl53lx".
The project is on git. See NRFconnect_out-of-tree_example
The root error is:
../src/modules/vl53lx/vl53lx.c: In function 'vl53lx_standby':
zephyr/include/generated/devicetree_unfixed.h:3877:29: error: 'DT_N_S_tof_S_tof_xshut_P_gpios_IDX_0_VAL_pin' undeclared (first use in this function); did you mean 'DT_N_S_leds_S_led_3_P_gpios_IDX_0_VAL_pin'?
#define DT_N_ALIAS_xshut DT_N_S_tof_S_tof_xshut
This macro failes:
#define TOF_XSHUT_PIN DT_GPIO_PIN(TOF_XSHUT_NODE, gpios)
In the «board.dts» is a snipped like:
#include <nordic/nrf52832_qfaa.dtsi>
/dts-v1/;
{
model = "TEST_BT NRF52832";
compatible = "nordic";
leds {
compatible = "gpio-leds";
led0: led_0 {
gpios = <&gpio0 17 GPIO_ACTIVE_LOW>;
label = "Green LED 0";
};
tof {
compatible = "st,vl53lx";
//compatible = "gpio-leds"; // HACK it works with that because the binding is in Zephyr tree
tof2: tof_xshut {
gpios = <&gpio0 7 GPIO_ACTIVE_LOW>; // BUG this definition does not exist
label = "Xshutdown active low";
};
};
}
In the "devicetree_unfixed.h" there is a difference between the tof GPIO and the LED ones:
The bindig is missing for the TOF
/*
* Devicetree node: /leds/led_0
*
* Node identifier: DT_N_S_leds_S_led_0
*
* Binding (compatible = gpio-leds):
* $ZEPHYR_BASE\dts\bindings\gpio\gpio-leds.yaml
*
* (Descriptions have moved to the Devicetree Bindings Index
* in the documentation.)
*/
/*
* Devicetree node: /tof
*
* Node identifier: DT_N_S_tof
*/
