Interrupt implementation for virtual EEPROM within I2C Target API

[gette95]

Hello everyone,

I'm currently working with the Microchip mec172xevb_assy6906 board running as an I2C Slave. For this project, I have created a device tree overlay.

&i2c_smb_0 {
	eeprom_i2c_slave: eeprom@54 {
		compatible = "zephyr,i2c-target-eeprom";
		reg = <0x54>;
		size = <0x400>;
		status = "okay";
		interrupts = < 0x19 0x1 >;
		interrupt-names = "i_veeprom";
	};
};

The virtual EEPROM eeprom_i2c_slave is linked to the I2C controller 'i2c_smb_0', that is configured as I2C target.

The interrupt is initialized with

IRQ_CONNECT( 
DT_IRQ_BY_NAME(DT_NODELABEL(eeprom_i2c_slave), i_veeprom, irq),   
DT_IRQ_BY_NAME(DT_NODELABEL(eeprom_i2c_slave), i_veeprom, priority),   
my_isr_handler,   
0,  
0);

and enabled

irq_enable(DT_IRQ_BY_NAME(DT_NODELABEL(eeprom_i2c_slave), i_veeprom, irq));

I can read the virtual EEPROM to get the received data, but the ISR handler (my_isr_handler) routine is never invoked.

Did I forget something here to get an interrupt when the virtual EEPROM receives data?

Or does anyone have experience with implementing an interrupt triggered I2C slave in Zephyr?
The virtual EEPROM is not mandatory.

Thanks for help!
