i2c-tegra: Retry transfer when unexpected status is detected 2011-01-29T03:36:49+00:00 Jin Park jinyoungp@nvidia.com 2011-01-19T05:41:42+00:00 6bab778a4b0caf58e464847c827d988a566bd434 Sometimes unexpected status like I2C busy status, Tx FIFO interrupted and wait on Rx data etc is seen. Add a code to detect such conditions and return -EAGAIN from driver. This will cause the i2c-core to retry the transmission as per the retry count and time-out specified by the platform data of the adapter.

i2c-tegra: add support for virtual busses with dynamic pinmuxing 2010-10-06T23:26:46+00:00 Gary King gking@nvidia.com 2010-07-14T01:56:40+00:00 67b5a6542fd3733c1b305512acd6407b6ab23d79 this adds support for dynamically reprogramming the I2C controller's pin mux on transaction boundaries to enable one controller to be registered as multiple I2C bus adapters with the kernel. this allows platform designers an additional tool to resolve clock rate, I/O voltage and electrical loading restrictions between the platform's peripherals. the i2c-tegra platform data is extended to support this; platforms which use this feature should pass in the number of busses which should be created for each controller, the starting adapter number to use and the clock rate and pin mux for each virtual bus.
