2019-07-31docs: i2c: convert to ReST and add to driver-api booksetMauro Carvalho Chehab1-12/+14
Convert each file at I2C subsystem, renaming them to .rst and adding to the driver-api book.

2018-05-17i2c: mux: gpio: move header to platform_dataWolfram Sang1-2/+2
This header only contains platform_data. Move it to the proper directory. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Acked-by: Peter Korsgaard <peter.korsgaard@barco.com>
2017-02-09i2c: i2c-mux-gpio: rename i2c-gpio-mux to i2c-mux-gpioPeter Rosin1-10/+10
The rename did the wrong thing for this documentation file all those years ago. Fix that as well as the neglected rename of the platform data structure.

2012-10-06i2c-mux-gpio: Update documentationJean Delvare1-0/+18
* Document the possibility to pass relative GPIO pin numbers. * Document what platform device IDs to use, so that they do not collide. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Peter Korsgaard <peter.korsgaard@barco.com>
2012-05-12i2c: Rename last mux driver to standard patternJean Delvare1-6/+6
Update the MAINTAINERS entry and all other references accordingly. Based on an original patch by Wolfram Sang. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Peter Korsgaard <peter.korsgaard@barco.com> [wsa: fixed merge conflict due to rework in i2c_add_mux_adapter()] Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
2011-01-11i2c: Add generic I2C multiplexer using GPIO APIPeter Korsgaard1-0/+65
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.
