i2c-xiic driver questions

Similar post in old thread elsewhere - thought I would make a new thread in the Linux forum - thanks

 

Seems the driver developers are _finally_ trying to address the read length issue of more then 255 bytes.

There are comments in the commits about going into standard mode for reads > 255. There is a comment about repeated start is not happening in dynamic mode.

Can someone clarify this? Are you saying that if I do a read of more than 255 then you will not do a repeated start read?

This is done because it is observed that
repeated start operation is not happening in dynamic mode read as
expected in a message set request from user space.
