Packed attribute is forcing a bytewise write on device registers,
there by, resulting in a misbehavior on gcc-4.4.1.
Reverting the structures to non-packed
If (just asking, not asserting) the issue is caused by fields being u8
where u8 access is not possible, then should you not make the fields u16
/ u32 according to access requirements?
The problem is not with the fields being of a different width. AFAIK,
the packed attribute changes the generated code to access even the word
field elements in a byte by byte manner
Infact, there is a discussion on lkml that I can point
https://lkml.org/lkml/2011/4/27/278
It seems that the discussion did not lead to a conclusion but it was
sensible (at least for ARM) to remove the packed attribute from this
structure

Vipin
Amicalement,
