Subject: media: chips-media: wave5: separate irq setup routine
Author: Ivan Bornyakov <brnkv...@gmail.com>
Date: Mon Apr 15 13:07:21 2024 +0300
Implement a separate setup routine for interrupts to reduce code
duplication. Also enable interrupts based on vpu_attr->support_encoders
and vpu_attr->support_decoders fields to facilitate support for other
Wave5xx IPs, because not all of them are both encoders and decoders.
