Hi
.
Also check the i2c_get_chip() function which you are using. See if
chip->offset_len is set to 1 as it should be, for your device. If not,
perhaps something is missing.
In short I am not really sure what is going on, but I think it needs
more investigation.

modify the designware_i2c_xfer function to use 1 byte per
address, it was set to 0 before which makes it think its
reading a register type. Added offset of where it is
supposed to read from. Before it was always reading from
offset 0 despite specifying the offset in the higher level
function.
