There was no problem without these patches though. With your patches, I see NAK happening on the I2C lines upon first 2-byte write.
Yes, but prior to these patches there were no register writes in sgtl5000.
These addditional writes does work and solve the reset issues on mx6qsabrelite/mx51evk.
It is only on mx28evk that we have this timeout issue.
I think we need to turn on the SAIF clock (that connects to the sgtl5000 MCLK) prior to doing the I2C writes.
