Hmm, you are probably right, given that I need this in the board DTS:
===
&i2c3 {
pinctrl-0 = <&i2c3_pins>;
pinctrl-names = "i2c-pwr";
+
+ /delete-property/ interrupts;
+ interrupts-extended = <&gic GIC_SPI 290 IRQ_TYPE_LEVEL_HIGH>, <&gpio1 26 IRQ_TYPE_EDGE_FALLING>;
+ interrupt-names = "main", "smbus_alert";
+
+ smbus;
};
===
I have to admit this is not exactly pretty. Pity, though, the I2C core
is all prepared for the above. Seems I have to update the core for
"alert-gpios", after all.
Happy hacking,
Wolfram
