Hi Geert,
IIUIC, this is not a property of the hardware, but a side-channel independent from the actual I2C controller hardware? Then a generic "smbus-alert-gpios" property sounds more appropriate to me.
It is not generic. While it is true that most I2C controllers do need GPIOs as a side channel, there are controllers having...
BTW, are you aware of any I2C controller having a dedicated input pin for this?
... this. Check 'i2c-stm32f7.c' or 'i2c-xlp9xx.c'. Thank you for your comments! Wolfram
