We would suggest you to find who is the actual vendor for this WLAN chip and use
the respective firmware vendor ID here.
BRCMF_SDIO_DEVICE(SDIO_DEVICE_ID_BROADCOM_CYPRESS_43752, CYW),
Also we are not the vendor for the other chip 43752 which is already listed here
with CYW firmware vendor ID. We will send a patch to remove 43752 from the list of
Infineon/Cypress supported WLAN chips.
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.
