This series adds the ability to associate a gpio with an I2C bus so that downstream devices can be brought out of reset when the host controller is probed. v5: https://lore.kernel.org/lkml/20231027033104.1348921-1-chris.packham@alliedtelesis.co.nz/ The conversation sparked from v5 was heading in the direction of this needing to be more generic. So I've moved the changes up to the i2c core, which is about as generic as I'm comfortable with.
