6 months ago The gpio api used is deprecated, should be changed to newer API. I don't know if Johan already did this, I have made an update, but still testing it. There are some more kernel changes that need to be checked.
// line 83 add:
static struct gpio_desc *gpio_desc; // top of the file// line 300 replace gpio part with :
gpio_desc = gpio_to_desc(gpioRxSamplesiPin);
if (!gpio_desc) {
printk("Failed to get GPIO descriptor\n");
return -ENODEV;
}
retval = gpiod_direction_input(gpio_desc);
if (retval) {
printk("Failed to set GPIO pin direction\n");
return retval;
}
printk(KERN_INFO "Radioberry: The rx sample state is currently: %d\n", gpio_get_value(gpioRxSamplesiPin));
// GPIO numbers and IRQ numbers are not the same! This function performs the mapping for us
// Get the IRQ number for the GPIO pin
irqNumber = gpiod_to_irq(gpio_desc);
if (irqNumber < 0) {
printk("Failed to get IRQ number for GPIO pin\n");
return irqNumber;
} // line 351 replace gpio_unexport with: gpiod_put(gpio_desc);

Today raspberry pi rolled out major apt update which upgrades kernel to 6.6. It breaks radioberry driver and it cannot be compiled anymore for both 32 and 64 versions.
compilation has 3 errors: 1) too many arguments for class_create(): Probably it can be fixed by removing first argument "THIS_MODULE," from the call.
2 and 3) functions gpio_export() and gpio_unexport() are not available anymore. It seems that it requires to use gpiod_export and gpiod_unexport but it uses different argument type and is not clear on how to use it:
Any info on how to fix it?
