From 92ed1a76ca31774eb27de14b2215841367c68056 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Mon, 10 Jan 2011 22:11:23 +0100 Subject: i2c: Add generic I2C multiplexer using GPIO API Add an i2c mux driver providing access to i2c bus segments using a hardware MUX sitting on a master bus and controlled through gpio pins. E.G. something like: ---------- ---------- Bus segment 1 - - - - - | | SCL/SDA | |-------------- | | | |------------| | | | | | Bus segment 2 | | | Linux | GPIO 1..N | MUX |--------------- Devices | |------------| | | | | | | | Bus segment M | | | |---------------| | ---------- ---------- - - - - - SCL/SDA of the master I2C bus is multiplexed to bus segment 1..M according to the settings of the GPIO pins 1..N.
