+Subject: [PATCH] MLKU-123-1 crypto: caam - add support for i.mx8mm, mn
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+TODO:
+
+1. clarify logic wrt. virtualization and DECORSR - see e-mail thread:
+"Register-based interface - DECORSR with virtualization disabled"
+
+2. check whether the clocks are identical for all mScale parts,
+and if they do use a single "i.MX8M*" entry in clocks array.
