Make the I2C adapter timeout configurable through a Device Tree property which gives the timeout in microseconds.My understanding is that software properties should not be defined via the device tree. I think a sysfs entry is more appropriate.
Is the timeout really a /software/ property? My feeling is that the timeout basically depends upon the bus clock and the chips attached to the bus. Therefore, it is linked closer to the composition of the board's hardware as described in the device tree, than to any userland software. Or am I totally wrong here? Thanks, Albrecht.
