Hi all, This series adds some resets for SMBus and for the I2C core. Along with it, we make SMBus slave error printing a little more helpful.
These reset issues were very infrequent, they would maybe occur in 1 out of hundreds of resets in our testing, but the way they happen is pretty straightforward. Basically as long as a reset happens in the middle of a transaction, the state of the old transaction would still partially be there after the reset. Once a new transaction comes in, the partial stale state can cause the new transaction to incorrectly fail.
