From where I can download this firmware image?

I suppose this FW bits have to be added to linux-firmware repository first, before this patch can be accepted.

All PS8640 devices should already ship with working firmware.
The firmware update procedure is only used in the unlikely event where
one wants to update the bridge to a different firmware provided by
Parade.

Why must the lack of firmware really block landing this driver?

If this is really so, can we just land the functional part of the
driver first, and add the firmware update in a follow-up patch.


After checking other users of request_firmware and check them against linux-firmware I think we don't need the FW in linux-firmware to get the driver merged. Especially as there already is a working FW stored on the device.
