Doug Anderson b81dfaa01f i2c: mux: Add i2c-arb-gpio-challenge 'mux' driver ... The i2c-arb-gpio-challenge driver implements an I2C arbitration scheme where masters need to claim the bus with a GPIO before they can start a transaction. This should generally only be used when standard I2C multimaster isn't appropriate for some reason (errata/bugs). This driver is based on code that Simon Glass added to the i2c-s3c2410 driver in the Chrome OS kernel 3.4 tree. The current incarnation as a mux driver is as suggested by Grant Likely. See <https://patchwork.kernel.org/patch/1877311/> for some history.
