From a2069aacbe58a8408a5bb0e0a722e1726456519b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Antoine=20T=C3=A9nart?= Date: Fri, 23 Jun 2017 16:05:25 +0200 Subject: [PATCH] crypto: inside-secure - do not parse the dma mask from dt Remove the dma mask parsing from dt as this should not be encoded into the engine device tree node. Keep the fallback value for now, which should work for the boards already supported upstream.
