i2c: muxes: add i2c gpio multiplexer driverAdd an i2c mux driver providing access to i2c bus segments using ahardware 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..Maccording to the settings of the GPIO pins 1..N.Note commit log from kernelcommit 92ed1a76("i2c: Add generic I2C multiplexer using GPIO API")Signed-off-by: Peng Fan Tested-by: Peng Fan (i.MX6QP-Sabreauto)Cc: Heiko Schocher Cc: Stefano Babic Cc: Simon Glass List of files: /rk3399_rockchip-uboot/drivers/i2c/muxes/Makefile

Mon, 25 Apr 2016 08:50:42 +0000

i2c: muxes: Add support for TI PCA954X muxAdd support for common TI i2c mux which is available on ZynqMP zcu102board.DM i2c mux core code is selecting/deselecting bus before/afterevery command is performed that's why only one channel is active at atime. That's also the reason why deselect is just disable all availablechannels.Signed-off-by: Michal Simek Reviewed-by: Heiko Schocher Reviewed-by: Simon Glass List of files: /rk3399_rockchip-uboot/drivers/i2c/muxes/Makefile

b725dc458f9db44957d4f541d05defe178dda7b5 - i2c: Add a mux for GPIO-based I2C bus arbitration

Mon, 03 Aug 2015 14:19:22 +0000

i2c: Add a mux for GPIO-based I2C bus arbitrationWhile I2C supports multi-master buses this is difficult to get right.The implementation on the master side in software is quite complex.Clock-stretching and the arbitrary time that an I2C transaction can takemake it difficult to share the bus fairly in the face of high traffic.When one or more masters can be reset independently part-way through atransaction it is hard to know the state of the bus.This driver provides a scheme based on two 'claim' GPIOs, one driven by theAP (Application Processor, meaning the main CPU) and one driven by the EC(Embedded Controller, a small CPU aimed at handling system tasks). Withthese they can communicate and reliably share the bus. This scheme hasminimal overhead and involves very little code. It is used on snow topermit the EC and the AP to share access to the main system PMIC andbattery. The scheme can survive reboots by either side without difficulty.This scheme has been tested in the field with millions of devices.Since U-Boot runs on the AP, the terminology used is 'our' claim GPIO,meaning the AP's, and 'their' claim GPIO, meaning the EC's. This terminologyis used by the device tree bindings in Linux also.Signed-off-by: Simon Glass List of files: /rk3399_rockchip-uboot/drivers/i2c/muxes/Makefile

Mon, 03 Aug 2015 14:19:21 +0000

dm: i2c: Add support for multiplexed I2C busesAdd a new I2C_MUX uclass. Devices in this class can multiplex betweenseveral I2C buses, selecting them one at a time for use by the system.The multiplexing mechanism is left to the driver to decide - it may becontrolled by GPIOs, for example.The uclass supports only two methods: select() and deselect().The current mux state is expected to be stored in the mux itself sinceit is the only thing that knows how to make things work. The mux canrecord the current state and then avoid switching unless it is necessary.So select() can be skipped if the mux is already in the correct state.Also deselect() can be made a nop if required.Signed-off-by: Simon Glass List of files: /rk3399_rockchip-uboot/drivers/i2c/muxes/Makefile
