From d6d022e7382343b57184c83f5fea0532be240b98 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 9 Oct 2012 19:28:00 -0300 Subject: [PATCH] Revert "[media] omap3isp: Replace cpu_is_omap3630() with ISP revision check" Reverted, as requested by Laurent: I don't consider it as being ready yet, as Sakari pointed out we need to investigate whether the right fix shouldn't be at the OMAP3 clocks level instead. This reverts commit 947c48086623d9ca2207dd0434bd58458af4ba86.
