Thanks for this work. If I read you correctly, this will depends on an scp
firmware update. Its probably early at rev1, but we appreciate if you can cross-
reference your associated linux-firmware submission (or document which MT
flavour of SCP firmware) contains this support already.
For ISP drivers reviewers, we have the experience with SCP that the IPC is not
versioned, making it difficult to maintain backward compatibility. Won't matter
until this is merged, but be aware that unless this SCP IPC design issue has
been fixed, any change to the -if headers means a modification to the SCP has
been made, and often we have had to ask MTK to revisit the firmware code to
unbreak backward compatibility.
If this specific part of the SCP IPC is versioned, please let us know. I don't
want this to be alarming message, just something we need to collectively be
aware of not to break userspace, which may not update their firmwares in lock
step with the kernel.
regards,
Nicolas
p.s. for those new to MTK architecture, the SCP firmware provides services to
everything multimedia in the platform, including CODECs, color converter and
scalers, etc.
