Ping?
The very old age of the firmware files in linux-firmware is really UNACCEPTABLE and very irresponsible from a security POV. Please fix this very soon.
If you do not reply to this email I see no choice but to switch the firmwares in linux-firmware over to the ones from the SDK which you do regularly update, e.g. those from: https://community.cypress.com/docs/DOC-19000
Yes those are under an older, slightly different version of the Cypress license, which is less then ideal, but that license is still acceptable for linux-firmware (*) and since you are not providing any updates to the special builds you have been doing for linux-firmware you are really leaving us no option other then switching to the SDK version of the firmwares.
Regards,
Hans
*) We have distributed files under the old version of the license before
