Probably both are Synaptics chipsets. Although the AP6398S(V) mentioned 
is a 43598 from Synaptics according the information from AMPAK [1]. 
Synaptics has not shown any interest in supporting their chipsets in 
linux upstream and I do not think that is likely to change. Indeed it 
seems incorrect to mark these as CYW. Probably WCC would be more 
appropriate, but I am not sure.
