Then the I2C client devices would have to be instantiated manually, I think it's more trouble. I could as well create custom I2C client drivers per ISP, but then the I2C devices would have to be represented somehow in DT, to pass stuff like voltage regulators and GPIOs. Anyway, it's not something could be done in mainline. Even if there is no actual I2C communication on the host CPU side, the power up/down sequence is handled there. The intention is to keep this common per an I2C client, regardless of whether I2C communication is done by firmware or the host the CPU. -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
