Subject: Revert "[media] omap3isp: Replace cpu_is_omap3630() with ISP revision check" Author: Mauro Carvalho Chehab <[email protected]> Date: Tue Oct 9 19:28:00 2012 -0300 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.
