-Kernel driver gpio-i2cmux
-
-Author: Peter Korsgaard <peter.korsgaard@barco.com>
-
-Description
------------
-
-gpio-i2cmux is an i2c mux driver providing access to I2C bus segments
-from a master I2C bus and a hardware MUX controlled through GPIO pins.
-
-E.G.:
-
-  ----------              ----------  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.
-
-Usage
------
-
-gpio-i2cmux uses the platform bus, so you need to provide a struct
-platform_device with the platform_data pointing to a struct
-gpio_i2cmux_platform_data with the I2C adapter number of the master
-bus, the number of bus segments to create and the GPIO pins used
-to control it. See include/linux/gpio-i2cmux.h for details.
-
-E.G. something like this for a MUX providing 4 bus segments
-controlled through 3 GPIO pins:
-
-#include <linux/gpio-i2cmux.h>
-#include <linux/platform_device.h>
-
-static const unsigned myboard_gpiomux_gpios[] = {
-	AT91_PIN_PC26, AT91_PIN_PC25, AT91_PIN_PC24
-};
-
-static const unsigned myboard_gpiomux_values[] = {
-	0, 1, 2, 3
-};
-
-static struct gpio_i2cmux_platform_data myboard_i2cmux_data = {
-	.parent		= 1,
-	.base_nr	= 2, /* optional */
-	.values		= myboard_gpiomux_values,
-	.n_values	= ARRAY_SIZE(myboard_gpiomux_values),
-	.gpios		= myboard_gpiomux_gpios,
-	.n_gpios	= ARRAY_SIZE(myboard_gpiomux_gpios),
-	.idle		= 4, /* optional */
-};
-
-static struct platform_device myboard_i2cmux = {
-	.name		= "gpio-i2cmux",
-	.id		= 0,
-	.dev		= {
-		.platform_data	= &myboard_i2cmux_data,
-	},
-};
