Subject: [PATCH 0/2] Delete the Qualcomm crypto engine
Date: Sat, 23 May 2026 15:03:55 -0400	[thread overview]
Message-ID: <20260523-delete-qce-v1-0-86105cd7f406@gmail.com> (raw)

The only realistic uses I can think of are:

1. Very weak devices where QCE is actually faster.
2. Devices without bitsliced NEON.

Do any such devices exist in the wild?  I have no idea.

Not even compile-tested, but should be trivial as it just deletes code.
I didn't change the device tree beyond marking the bindings as
deprecated.
