Subject: [PATCH 00/11] accel: ethosu: Another batch of fixes
Date: Thu, 27 Aug 2026 15:32:59 -0500	[thread overview]
Message-ID: <20260827-ethosu-fixes-v1-0-346f9ea8791c@kernel.org> (raw)

This is another series of fixes to the ethosu driver. It's mostly probe 
error paths and cmd stream validation fixes. It's a mixture of 
AI reported issues, different solutions to other posted issues and 
fixes[1] and my own fixes.

The series adds rejecting OFM tranpose in cmd stream, but then the last 
patch adds support for it. I did this so the rejection can be 
backported, but maybe supporting OFM transpose is small enough that it 
should just be backported too?
