[PATCH v3 20/29] media: iris: subscribe parameters and properties to firmware for hfi_gen2

Dikshita Agarwal via B4 Relay
2024-08-27T10:06:36Z

From: Vedang Nagar <quic_vnagar@quicinc.com>

For hfi_gen2, subscribe for different bitstream parameters to
firmware to get notified for change in any of the subscribed
parameters.
