From 9a9ded89ad9ca46382a4ea63f36f830bccfab4ec Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Tue, 13 Jun 2017 11:28:45 +0200 Subject: [PATCH] ARM: OMAP4: hwmod data: add aes1 This fixes the following error during kernel boot: platform 4b501000.aes: Cannot lookup hwmod 'aes1' Unfortunately the AES module is only documented partly in the OMAP4430 TRM. I found an old patch from Joel, which I took over and updated for currently mainline.
