[PATCH 2/2] media: iris: Enable Gen2 HFI on SC7280
From: Dikshita Agarwal
Date: Mon Feb 09 2026 - 04:50:02 EST
SC7280 supports both Gen1 and Gen2 HFI firmware. The driver continues to
use Gen1 by default, but boards that intend to use Gen2 firmware can
opt‑in by specifying a Gen2 image through the Device Tree
'firmware-name' property.
Based on this property and the availability of the referenced
firmware binary, the driver selects the appropriate HFI generation and
updates its platform data accordingly. Boards that do not
specify a Gen2 firmware, or where the firmware is not present,
automatically fall back to Gen1.
