I could imagine that we design a generic property for filters. The ones above make me wonder, though, because they are bool. I'd think you can configure the filters in some way, too? I never used such filtering, so I am unaware of the parameters needed / suitable. Quick grepping through I2C master drivers reveals that i2c-stm32f7.c also handles filters, but only with default values. Maybe DT configuration would be benefitial to that driver, too?
