From eee543e8248150e8fb833943c71f40c7b1724600 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 5 Oct 2012 22:23:51 +0200 Subject: i2c-mux: Add support for device auto-detection Let I2C bus segments behind multiplexers have a class. This allows for device auto-detection on these segments. As long as parent segments don't share the same class, it should be fine. I implemented support in drivers i2c-mux-gpio and i2c-mux-pca954x. I left i2c-mux-pca9541 and i2c-mux-pinctrl alone for the moment as I don't know if this feature makes sense for the use cases of these drivers.
