From ebea90df78c1f290529e18b85c19653e131954de Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Tue, 13 Jun 2017 11:28:47 +0200 Subject: [PATCH] ARM: OMAP4: hwmod data: add des This fixes the following error during kernel boot: platform 480a5000.des: Cannot lookup hwmod 'des' Unfortunately the DES 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.
