wifi: brcmfmac: fix 43752 SDIO FWVID incorrectly labelled as Cypress (CYW)

2025-09-03T08:08:04Z

Cypress(Infineon) is not the vendor for this 43752 SDIO WLAN chip, and so has not officially released any firmware binary for it. It is incorrect to maintain this WLAN chip with firmware vendor ID as "CYW". So relabel the chip's firmware Vendor ID as "WCC" as suggested by the maintainer.

wifi: brcmfmac: support CYW54591 PCIE device

2025-07-21T17:36:09Z

CYW54591 is a variant of BCM4355 silicon with the same chipid. In the chipid-fwname mapping table, apply chiprev 13 to identify CYW54591. Skip reading OTP process for CYW chip since it contains vendor specific information which is not common for cypress.

wifi: brcmfmac: add flag for random seed during firmware download

2024-09-18T13:53:48Z

Providing the random seed to firmware was tied to the fact that the device has a valid OTP, which worked for some Apple chips. However, it turns out the BCM43752 device also needs the random seed in order to get firmware running. Suspect it is simply tied to the firmware branch used for the device. Introducing a mechanism to allow setting it for a device through the device table.

Assume the right cutoff point for firmware versions is revision ID 11 then, and leave older revisions using the non-versioned firmware filename (Apple only uses C1 firmware builds).

wifi: brcmfmac: Rename Cypress 89459 to BCM4355

2023-02-13T16:50:51Z

The commit that introduced support for this chip incorrectly claimed it is a Cypress-specific part, while in actuality it is just a variant of BCM4355 silicon (as evidenced by the chip ID). The relationship between Cypress products and Broadcom products isn't entirely clear but given what little information is available and prior art in the driver, it seems the convention should be that originally Broadcom parts should retain the Broadcom name. Thus, rename the relevant constants and firmware file. Also rename the specific 89459 PCIe ID to BCM43596, which seems to be the original subvariant name for this PCI ID (as defined in the out-of-tree bcmdhd driver). Since Cypress added this part and will presumably be providing its supported firmware, we keep the CYW designation for this device. We also drop the RAW device ID in this commit. We don't do this for the other chips since apparently some devices with them exist in the wild, but there is already a 4355 entry with the Broadcom subvendor and WCC firmware vendor, so adding a generic fallback to Cypress seems redundant (no reason why a device would have the raw device ID *and* an explicitly programmed subvendor).
