Subject: [PATCH resend] ocfb: fix tgdel and tvdel timing parameters
Date: Tue, 26 Jan 2016 14:48:04 +0000 [thread overview]
Message-ID: <1453819684-32742-1-git-send-email-andrea.merello@gmail.com> (raw)
According to the ocfb documentation:
Fix tgdel HW param should be left margin, not right.
Fix tvdel HW param should upper margin, not lower.
This seems to fix lock issues on certain monitors (tested on a
slightly customized IP, but the FPGA guy said that it should
be the same wrt this changes).
