[PATCH] media: venus: firmware: Use correct reset sequence for IRIS2
Posted by Stephan Gerhold 1 month, 2 weeks ago 
When starting venus with the "no_tz" code path, IRIS2 needs the same
boot/reset sequence as IRIS2_1. This is because most of the registers were
moved to the "wrapper_tz_base", which is already defined for both IRIS2 and
IRIS2_1 inside core.c. Add IRIS2 to the checks inside firmware.c as well to
make sure that it uses the correct reset sequence.

Both IRIS and IRIS2_1 are HFI v6 variants, so the correct sequence was used
before commit c38610f8981e ("media: venus: firmware: Sanitize
per-VPU-version").

Fixes: c38610f8981e ("media: venus: firmware: Sanitize per-VPU-version")
